Page 51: Externally Leveling The Swept Signal Generator
Externally Leveling In externally leveled operations, the output power from the swept signal generator is detected by an external sensor. The output of this the Swept Signal detector is returned to the leveling circuitry, and the output power Generator is automatically adjusted to keep power constant at the point of detection.
Page 52 Power splitters have a coupling factor of 0 dB. Figure 1-12 shows the input power versus output voltage characteristics for typical HP diode detectors. From the chart, the leveled power at the diode detector input resulting from any external level voltage setting may be determined. The range of power adjustment is approximately -30 dBm to +18 dBm.

Leveling with a Power Meter 1. Set up the equipment as shown. Be sure to set the power meter to manual range mode and note the range.
Page 56: Leveling With Mm-Wave Source Modules
Leveling with MM-wave Millimeter-wave source module leveling is similar to power meter leveling. The following figures illustrate the setups for leveling with a Source Modules mm-wave source module. Figure l-14. MM-wave Source Module Leveling High power model swept signal generators can externally level mm-wave source modules to maximum specified power without a microwave amplifier.

Page 58: Working With Mixers/Reverse Power Effects
Working with Mixers/Reverse Power Effects Note Uncoupled operation applies to Option 001 swept signal generators only. Uncoupled operation is useful when working with mixers. Figure 1-16 shows a hypothetical setup where the swept signal generator is providing a small signal to a mixer. The swept signal generator output is -8 dBm, which in Leveling Mode Normal results in LO of +lO dBm, and has LO to RF isolation of 15 dB.

Page 60: Working With Spectrum Analyzers/Reverse Power Effects
Reverse power is a problem with spectrum analyzers that do not have preselection capability. Some analyzers have as much as Analyzers/Reverse frequencies. The effects of reverse power are less in the heterodyne Power Effects band (0.01 to 2.0 GHz) where the power amplifier provides some broadband matching.
Page 61: Optimizing Swept Signal Generator Performance
There are two basic front-panel methods of creating a flatness correction array. The first and quickest method is to use an HP 437B power meter. Refer to Figure 1-18 for the setup. The second method is just as accurate, but requires a little more interaction between the operator and the instruments.
Page 62: Creating A User Flatness Array Automatically, Example 1
Creating a User Flatness Array Automatically, Example 1 In this example, a flatness array containing correction frequencies from 4 to 10 GHz at 1 GHz intervals is created. An HP 438B power meter controlled by the swept signal generator through the interface bus is used to enter the correction data into the flatness array.
Page 63 If an HP-IB error message is displayed verify that the interface connections are correct. Check the HP-IB address of the power meter and ensure that it is the same address the swept signal generator is using (address 13 is assumed).
Page 64: Creating A User Flatness Array, Example 2
Creating a User Flatness Array, Example 2 This example shows how to use the swept signal generator and a power meter in manual entry mode. This example also introduces two features of the swept signal generator. The softkey Freq Follow simplifies the data entry process and the softkey List Mode sets a list of arbitrary test frequencies.

Page 67: Swept Mm-Wave Measurement With Arbitrary Correction Frequencies, Example 3
Example 3 The focus of this example is to use user flatness correction to obtain flat power at the output of the HP 83550 series mm-wave source modules. In this case we will use non-sequential correction frequencies in a swept 26.5 to 40 GHz measurement with an HP 83554 source module.

Creating Arbitrarily Spaced Frequency-Correction Pairs in a Swept mm-wave Environment For this example, refer to menu map 5, POWER. 1. The equipment setup shown in Figure l-20 assumes that you have followed the steps necessary to correctly level the configuration.
Page 69 Note U, V, and W-band power sensors are not available from Hewlett-Packard. For these frequencies use the Anritsu ML83A Power Meter with the MP715-004 (40 to 60 GHz), the MP716A (50 to 75 GHz), or the MP81B (75 to 110 GHz) power sensors. Since the Anritsu model ML83A Power Meter is not capable of internally storing power sensor cal factors, you must manually correct the data entry.
Page 70 If an HP-IB error message is displayed verify that the interface connections are correct. Check the HP-IB address of the power meter and ensure that it is the same address the swept signal generator is using (address 13 is assumed).
Page 71: Scalar Analysis Measurement With User Flatness Corrections, Example 4
Example 4 The following example demonstrates how to set up a scalar analysis measurement (using an HP 8757 Scalar Network Analyzer) of a 2 to 20 GHz test device such as, an amplifier. User flatness correction is used to compensate for power variations at the test port of a directional bridge.
Page 72 The user flatness correction array cannot be stored to a disk. You must make sure that the array is stored in one of the eight internal registers. Recalling a file from an HP 8757 disk will not erase the current array; therefore you may recall an array from an internal register, then recall an associated file from a disk.

Page 76 If an HP-IB error message is displayed verify that the interface connections are correct. Check the HP-IB address of the power meter and ensure that it is the same address the swept signal generator is using (address 13 is assumed).
Page 77: Using The Tracking Feature
Using the Tracking Peaking Feature Peaking is the function that aligns the output filter (YTM) so that its passband is centered on the RF output, in CW or manual-sweep mode. Use peaking to obtain the maximum available power and spectral purity, and best pulse envelopes, at any given frequency above 2.0 GHz.
Page 78: Alc Bandwidth Selection
ALC Bandwidth The ALC bandwidth defaults at factory preset to the auto selection ALC Bandwidth Select Auto which selects appropriate Selection bandwidth (high or low) for each application. To make the bandwidth selection, the swept signal generator determines which functions are activated and uses the decision tree shown in Figure l-23.

REMOTE annunciator is lighted. The syntax is: where the device selector is the address of the instrument appended to the HP-IB port number. Typically, the HP-IB port number is 7, and the default address for the swept signal generator is 19, so the device selector is 719.
Page 87: Local
Related statements used by some computers: RESUME Clear Clear causes all HP-IB instruments, or addressed instruments, to assume a “cleared” condition, with the definition of “cleared” being unique for each device. For the swept signal generator: 1. All pending output-parameter operations are halted.
Page 88: Output
Some BASIC examples: CLEAR 7 to clear all HP-IB instruments, or CLEAR 719 to clear an addressed instrument. Related statements used by some computers: RESET CONTROL SEND The preceding statements are primarily management commands that do not incorporate programming codes. The following two statements do incorporate programming codes, and are used for data communication.
Page 89: Enter
A BASIC example: 100 OUTPUT 719; “programming codes” The many programming codes for the swept signal generator are listed in the “SCPI Command Summary” in Chapter 2. Related statements used by some computers: CONTROL CONVERT IMAGE IOBUFFER TRANSFER Enter Enter is the complement of OUTPUT, and is used to transfer data from the addressed instrument to the controller.
Page 90 ASCII CR (carriage return), comma, or semicolon might cause a false termination. Suppression of the EOL causes the computer to accept all bit patterns as data, not commands, and relies on the HP-IB EOI (end or identify) line for correct end-of-data termination.
Page 91: Getting Started With Scpi
An instrument is any device that implements SCPI. Most instruments are electronic measurement or stimulus devices, but this is not a requirement. Similarly, most instruments use an HP-IB interface for communication. The same concepts apply regardless of the instrument function or the type of interface used.

Page 265 Function Group (MOD) Menu Map 4 Description This softkey (Option only) lets you output the internally- generated frequency modulation waveforms to the rear panel AM/FM OUTPUT connector. When scaled exponentially at 10 dB/V, the maximum output voltage is offset to 0 V and the minimum voltage level is -4 V.
Page 266 Modulation Modulation The swept signal generator’s amplitude and pulse modulation General Circuit Theory performance is directly tied to the ALC (Automatic Level Control) system. Refer to the ALC block diagram in Figure M-l. The ALC system controls the amplitude or power level of the RF output. A portion of the output signal is detected, summed with the reference level signal, and the difference (error) signal drives an integrate-and-hold circuit.
Page 267: Amplitude Modulation
A jumper on the A10 ALC board allows you to change the input HP 8360 B-Series impedance to 2 kR (See “Adjustments” in the Swept Signal Generator/HP 8360 L-Series Swept CW Generator Service Guide.) The AM can be scaled either linearly at 100% per volt or exponentially at 10 dB per volt.
Page 268 Amplitude Modulation giving 0 dBm output power and greater AM depth potential. The ALC can now be varied over its entire range and the attenuator remains at a fixed level. Uncoupled mode can also be used for the following: minimum power range of the ALC loop. To offset the power sweep range.
Page 269 Amplitude Modulation for an message.) The minimum level is limited by the detector’s range (approximately -20 dBm). With deep AM engaged, the minimum level (where the ALC loop is opened) is set to -13 dBm. This guarantees that the detector can still sense the signal level with no distortion.

All FM Driver board allows you to change the input impedance to HP 8360 B-Series Swept Signal 600 R. (See “Adjustments” in the Generator/HP 8360 L-Series Swept CW Generator Service Guide.) The FM sensitivity can be scaled to either 100 kHz/V, 1 MHz/V, or 10 MHz/V.
Page 271 FM Modulation The maximum FM deviation is limited by the following two conditions: Maximum FM deviation must be less than 8 MHz Maximum FM deviation must be less than n x 5 x FM rate (refer to the “Frequency Bands” specification for the value of n).

Page 453: Instrument Preset Conditions For The Hp
HP 8340/8341. Instrument Preset Conditions. The factory defined preset conditions for the HP 8360 B-Series are identical to those for the HP 8340/8341. The HP 8360 B-Series also allows you to define a different set of preset conditions.
Page 454 AUXILIARY INTERFACE The dedicated HP 8510 versions of the HP 8360 (HP 83621B, HP 83631B) may b e configured to power-up to one of two possible system languages, network analyzer language, or SCPI (Standard Commands for Programmable Instruments). This configuration is controlled via a switch located on the rear panel of the instrument.
Page 455 HP 8340/8341. The HP 8360 B-Series differs from the HP 8340/8341 in one connection only. It is unnecessary to connect the modulator drive signal from the analyzer to the source. The HP 8360 B-Series internally produces the 27.8 kHz modulated signal necessary for AC mode measurements on the analyzer.
Page 456: Test And Measurement System Language
Control Interface Intermediate Language CIIL is the instrument control programming language used in Option 700 HP 8360 B-Series. Like the HP 8340/8341 E69, the Option 700 HP 8360 B-Series is M.A.T.E.-compatible. Refer to the HP 8360 Option 700 Manual Supplement for information on this option.

Routine Routine maintenance consists of replacing a defective line fuse, cleaning the air filter, cleaning the cabinet, and cleaning the display. Maintenance These items are discussed in the following paragraphs. Table 4-1. Fuse Part Numbers WARNING For continued protection against fire hazard replace line fuse only with same type and rating.
Page 467: How To Clean The Fan Filter
How to Clean the Fan The cooling fan located on the rear panel has a thin foam filter. How often the filter must be cleaned depends on the environment Filter in which the swept signal generator operates. As the filter collects dust, the fan speed increases to maintain airflow (as the fan speed increases, so does the fan noise).
Page 468: How To Clean The Cabinet
How to Clean the Cabinet Warning To prevent electrical shock, disconnect the HP 8360 B-series swept signal generator from the mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
