3.7.5. OUTPUT PROGRAMMING
3.7.5.1.OUTPUT VOLTAGE AMPLITUDE (AMP)
The AMP header with the optional A, B or C extension is used to identify the amplitude
command. The argument is a numeric data field from 0.0 to the limit set by the RNG value.
An attempt to program a value higher than this value will generate an error and a SRQ on the
GPIB.
The following ASCII strings will program the voltage given in the left column:
A,B,C 0.0 volts AMP0 or AMPA0AMPB0AMPC0
A,B,C 10.5 volts AMP10.5 or AMP1.05E1 or AMP105E-1
A,B,C 100 volts AMP100 or AMP100.0 or AMP1E2
A,B = 110.5, C = 115 AMPA110.5AMPB110.5AMPC115
or
AMP110.5AMPC115
3.7.5.2.FREQUENCY (FRQ)
The FRQ header is used to identify the following numeric data as frequency.
The following string will program the frequency to 60.56 Hz.
FRQ 60.56
3.7.5.3.PHASE ANGLE (PHZ)
The PHZ header with the optional A, B or C extension is used to identify the following
numeric data as phase. The PHZ header sent with no extension will program the B and C
outputs to the same value relative to the phase A output. The phase of the A output will lead
the EXT SNC signal by the value programmed.
The following example will program the phase A output to 90 degrees relative to an external
sync signal when operating in the EXT SNC mode:
PHZA 90
