Agilent Technologies Multiple Channel Controller 85330A - Manual (Page 80)

6-6 85330A Multiple Channel Controller
Programming
Single Source Multiple-Frequency Configuration
This setup allows the 8530A to measure each receive switch input in
sequence. Each one is measured as a separate parameter, which you can read
using the system computer. Refer to the GPIB Programming chapter of the
Agilent 8530A Operating and Programming Manual for detailed
information.
•
Select external triggering with TRGEXT . This is equivalent to pressing
STIMULUS {MENU} {MORE} {TRIGGER MODE} {TRIG SRC EXTERNAL} . This
command is described in the Stimulus chapter of the Agilent 8530A
Operating and Programming Manual.
•
Set the 8530A so it waits for a trigger before measuring each parameter.
You can do this by issuing
PAR1TON, PAR2TON, PAR3TON, and PAR4TON . This
is equivalent to pressing STIMULUS {MENU} {MORE} {TRIGGER MODE} , then
ensuring that {PARAM 1}, {PARAM 2}, {PARAM 3} , and {PARAM 4} are activated
(underlined). These commands are described in the Stimulus chapter of
the Agilent 8530A Operating and Programming Manual.
You only have to send the PARTON commands that relate to the parameters
that are actually being measured. For example, if you are only measuring
Parameter 1 and Parameter 2,
PAR1TON and PAR2TON are the only two
commands that must be executed.
NOTE You can issue all four of these commands even if you are measuring only
two or three parameters. The extra commands will simply be ignored.
85330A settings
•
When the source is under 8530A control, the multiple channel controller
must be set to the IMMediate triggering mode:
RUNT:SOUR:SOURCE1:TRIG IMM;
•
Use GPIB address 19 for the RF source.
