1. pow (Power Level) Equipment Required: Power meter connected to Dedicated GPIB port
Power sensor with appropriate frequency range
Throughline
Header Section Keywords
ncal Number of calibration sequences of this type to run. For type = pow, each
sequence consists of:
linear cal (for power sweeps)
flat power cal
receiver cal
NOTE: Since this attempts to be a "global" power level calibration, ncal should
get a value of 1.
npts Number of frequency points to use during the calibration sequence. Increasing
this number will increase calibration time.
Legal values are (3, 15, 51, 101, 201, 401, 801, 1601 only
)
NOTE: Illegal value causes software to default to 51.
if IF bandwidth: Legal values are 10, 30, 100, 300, 1000, 3000, 10000, 30000
NOTE: Illegal value causes software to default to 1000.
avgs Averages: (Optional). Software will set averaging to value (and turn on) during cal.
pow Source setting for each source during flat power cal.
target Target power setting for each source during flat power cal.
noffset Nominal offset value for use during linear cal.
NOTE: During linear cal the software attempts to calibrate the sources from
-15 dBm to +5 dBm at the input reference plane.
switch Setting for test set. Correponds to 0-15 settings.
