Argument
Set Channel A Offset / none
(s = polarity; n = dB offset; -40.00 min +90.00 max)
Set Channel B Offset / none (See OFFA)
Select Dual Channel Mode: Peak Power Both Channels / none
Select Channel A Only: Peak Power Mode / none
Select Channel B Only: Peak Power Mode / none
Set Code Number to be Plotted / none
(x = ASCII string of 12 characters or less)
Plot Pulse Profile Currently Displayed GPIB interface must be managed correctly.
PPM will output pulse profiles with relevant marker information (or without if
desired) using HPGL graphics codes to a compatible digital plotter. See Plot Output
Mode in Section 3.2.5 for plotting instructions.
Set Part Number to be Plotted / none
(x = ASCII string of 12 characters or less)
Change to Marker Sub-Mode and immediately begin plotting / See PLOT
(This command ensures that the placement of markers is based on the same power
measurement data as is sent to the plotter for increased accuracy of marker
placement on the hardcopy plot.)
Plot Pulse Profile Currently Displayed at Slower Speed for Transparencies / Same as
PLOT but slower pen speed.
Measure and Output Pulse Width of Pulse Profile Currently Displayed (50% point on
rising edge of pulse to 50% point on the falling edge of the pulse). This command
erases previously set markers / The PPM will output the following string when
operating in channel A:
WIDAnn.nnnEsnn
For channel B:
WIDBnn.nnnEsnn

Set Channel A Reference Power for Graphic Display / none
(s = polarity; n = dBm value; +110.00 max -60.00 min)
Set Channel B Reference Power for Graphic Display
(s = polarity; n = dBm value; +110.00 max -60.00 min)
Change to Marker Sub-Mode and plot at Slower Speed for Transparencies / Same as
PLTT but with slower pen speed.
Set Pulse Fall Time - End % / none
[n = % expressed in 0.1% units; 1 to 999 (0.1% to 99.9%)]
Set Pulse Fall Time - Start % / none
[n = % expressed in 0.1% units; 1 to 999 (0.1% to 99.9%)]
Measure and output fall time of the pulse profile displayed in the Pulse Parameters
sub-mode. / The PPM will output the following string when operating in Channel A:
FALAnnnnn.nEsnn
For Channel B:
FALBnnnnn.nEsnn
(n = seconds; Esnn = exponent; s = polarity)
PULA
Select Channel A only: Pulse Parameter submode / none
