Performance Tests Model 3336A/B/C
**NOTE
Directional Bridges are also part of Transmission/Reflection Kits:
50 ohm Transmission/Reflection Kit -hp- Model 11652A
75 ohm Transmission/Reflection Kit -hp- Model 11652A
Option 008
a. Connect the equipment as shown in Figure 4-7. Use the appropriate impedance Direc-
tional Coupler and Termination for the output under test. For example, to test the 124 ohm
output, use the 124 ohm Directional Coupler and 124 ohm Termination Resistors. To test
the 75 ohm output, use the 75 ohm Direction Coupler and 75 ohm Feedthru Terminations.
NOTE
Make sure the frequency references of the synthesizer and the 3336
(DUT) are locked together.
b. Set the 3336 (DUT) output amplitude to maximum:
50 ohm — +8.76 dBm
75 ohm — +7.00 dBm
124 ohm — +1.76 dBm
150 ohm — +1.76 dBm
c. Set the 3336 (DUT) output frequency to one of the following test frequencies:
50 ohm — 100kHz, 1MHz, 10MHz, 20.9MHz
75 ohm — 100kHz, 1MHz, 10MHz, 20.9MHz
124 ohm — 100kHz, 1MHz, 10.9MHz
150 ohm — 100kHz, 1MHz, 2.09MHz
e. Set the reference synthesizer's output amplitude to — 10 dBm for all test setups except
when testing the 3336's 75 ohm output. Set the reference synthesizer's output amplitude to
—4 dBm when testing the 75 ohm outputs.
f. Set the reference synthesizer's output frequency to the test frequency (selected in Step
c) plus 15 Hz.
