6.9 Calibration
6.9.1.26 Cal Type
Specifies how the calibration is to be performed on the selected Cal. Options are;
–
MAGNitude: A single CW tone is measured at the center of the screen for each
frequency point
–
COMPlex: A comb signal is measured across the full IF passband at each
frequency point. Magnitude and Phase are measured
Remote Command
:SYSTem:CALibration:ROW[1]|2|…|100:TYPE MAGNitude | COMPlex
:SYSTem:CALibration:ROW[1]|2|…|100:TYPE?
Example
:SYST:CAL:ROW2:TYPE COMP
Dependencies Only available if the selected RCal module has a license for complex calibrations. If it does not, this
control is disabled
The SCPI command applies to the currently selected Cal Group
If the subopcode does not reference an existing Cal row in the Cal Group, the error message “-221,
Settings conflict; Subopcode does not reference an existing Cal row” is generated

6.9.1.27 Start Freq
Specifies the start frequency of the selected Cal.
Remote Command
:SYSTem:CALibration:ROW[1]|2|…|100:FREQuency:STARt <freq>
:SYSTem:CALibration:ROW[1]|2|…|100:FREQuency:STARt?
Example
:SYST:CAL:ROW2:FREQ:STAR 1e9
Notes Max values depend on Hardware Options (503, 507, 508, 513, 526)
Dependencies The SCPI command applies to the currently selected Cal Group
If the subopcode does not reference an existing Cal row in the Cal Group, the error message “-221,
Settings conflict; Subopcode does not reference an existing Cal row” is generated
By direct entry:
You cannot set Start Frequency > Stop Frequency. You can set the Start frequency = Stop frequency.
If you set Start Frequency = Stop Frequency, "Freq Step" on page 2193 is adjusted to 0, and "Freq
Points" on page 2193 is adjusted to 1
With the knob or step keys:
If you set Start Frequency = Stop Frequency, Freq Step is adjusted to 0, and Freq Points is adjusted to
1
Couplings If you change the start frequency of the selected range to a value > the range’s stop frequency, the
