Command Argument
RPOA Read Out Current Channel A Reference Power / The PPM will output channel A
reference power in the following format:
If operating in the Linear Power Mode:
RFALxx.xxEsnn
(x = power in Watts; Esnn = exponent)
If operating in the dBm power format:
RFADsnnn.nn
(s = polarity; n = reference power in dBm)
RPOB Read Out Current Channel B Reference Power. (Readout is the same as RPOA,
substituting B or A)
RSFL Measure and Output Rise and Fall Times of Pulse Profile Currently Displayed. See
FALL and RISE for definitions used for fall and rise times / When operating in
channel A the PPM will output:
RISAnn.nnnEsnn,FALAnn.nnnEsnn
When operating in channel B:
RISBnn.nnnEsnn,FALBnn.nnnEsnn
(n = delay in seconds; Esnn = exponent)
RSWD Measure and Output Rise time and Pulse Width of Pulse Profile Currently Displayed.
See RISE for definition of rise time. Pulse width is the time between the 50% power
point on the pulse’s rising edge and the 50% point on it’s falling edge / Channel A
readout is:
RISAnn.nnnEsnn,WIDAnn.nnnEsnn
Channel B readout is:
RISBnn.nnnEsnn,WIDBnn.nnnEsnn
SDLAnnnnnn.nn Set Channel A Start Delay / none
(n = microseconds; position of decimal may vary.
Max = 213,999.97
µ
s - Window Delay - Reference Delay;
Min = 0 - Reference Delay.
Start Delay is with respect to the Reference Delay. If Reference Delay is 0 then Start
Delay is coincident with the trigger.)
SDLBnnnnnn.nn Set Channel B Start Delay / none (see SDLA)
SELT Initiate Self-Test. Can be used with SRQ for a health check. See Service Requests in
Section 3.4.
SRQD SRQ Disable. See Service Requests in Section 3.4
SRQE SRQ Enable. See Service Requests in Section 3.4
STAT Output Status Byte. This command is only effective when SRQ is disabled. If sent
while SRQ is enabled an SRQ will be generated. The PPM will output:
STATnnn
(n = decimal number representing current Status Byte. See Status Byte Output in
Section 3.2.5 and Service Requests in Section 3.4)
