Model 5355A
Operation and Programming
3-62.
Address Selection
3-63.
The 5355A must be assigned a bus address. Table 3-8 gives the allowable address switch
settings. The setting of switches Ai through As defines the addresses. The listen address
{Table 3-8) is used to program the functions of the 5355A.
3-64.
Before learning the programming details of the 5355A, some knowledge of 5345A
programming is required, as described below.
3-65.
Programming the 5355A/5345A
3-66.
The 5355A is programmed for remote control of all its operating modes by the codes
shown in Table 3-9. The 5355A operates remotely only in the listen function and does not output
to the HP-IB.
3-67.
Measurement data from the 5355A is sent to the 5345A for processing and display. This
information is sent to the HP-IB via the talk output of the 5345A which must be programmed by
the codes shown in the 5345A Operating and Service Manual, except as described in paragraph
3-68 below.
NOTE
5345A program codes E9 and J1 are invalid when the
5355A is plugged in, as detailed in the following
paragraph.
3-68.
INVALID 5345A PROGRAM CODES.
The 5345A program codes E9 (Sample Rate Hold)
and J1 (Sample Trigger Command) are invalid when the 5355A is plugged into the 5345A. These
functions are performed by programming the 5355A plug-in using the Hold code, i.e., HD0
selects the 5345A Sample Rate and HD1 is used in place of the normal 5345A code E9 for Sample
Rate Hold. (Refer to Table 3-9).
NOTE
When the 5345A is operating in remote control, the
rear panel GATE CONTROL INPUT switch function
must be programmed according to the operating
mode of the 5355A. The 5345A must be programmed
for External Gate (E;) when the 5355A is in the pulse
mode of operation. The 5345A must be programmed
for Internal Gate (E3) when the 5355A is in the CW
mode of operation.
3-69.
Status Display
3-70.
The status of the 5355A operation is shown on the display of the 5345A when program
code R (Read Status) is sent to the 5355A. The display contains a digit in each position that
indicates the mode of operation (first 8 digits) the head code (9th digit) and the error code or
diagnostic mode (10th and 11th digits) as illustrated in Table 3-70. The head code indicates which
Frequency Converter Head is installed. The error codes are described in paragraph 3-54.
Diagnostic modes are described in Table 3-11.
3-21
