See Table: Trace Parameters and Coefficients for a complete listing of trace graph types, default settings, and available ranges.
Working with Dual-Display Rectangular Trace Formats
This command is primarily designed to be used to set the per-division (PDIV) scale value on one of the VectorStar VNA dual-display trace formats. There are four dual-display trace formats:
• Linear Magnitude and Phase (LINPHase)
• Log Magnitude and Phase (LOGPHase)
• Real and Imaginary (REIMaginary)
• Impedance Real and Imaginary (ZCOMPlex)
Working with Single-Display Rectangular or Polar Trace Formats
If the trace is a single-trace non-Smith Chart display, this command can also set the per-division scale value on single trace displays including rectangular and polar graph trace formats.
Working with Smith Chart Trace Displays
If the trace type is a Smith Impedance Chart or a Smith Admittance Chart, the available scale values are limited to the values of +3dB, 0dB, -10dB, -20dB, -30dB. These are the only values permitted and other entered values result in an execution error.
Cmd Parameters
For Smith Charts: <NRf> 3 | 0 | -10 | -20 | -30
Where:
• 3 = +3dB compressed Smith Chart
• 0 = 0 dB standard Smith Chart
• -10 = -10 dB expanded Smith Chart
• -20 = -20 dB expanded Smith Chart
• -30 = -30 dB expanded Smith Chart
For all other displays: <NRf>
Query Parameters
<NR3> The output parameter units varies depending on the trace display type.
For Smith Charts, the output parameter is based on the outside radius of the outer circle. For all other trace displays, the output is in one of the following:
• dB per division
• Hertz per division
• Meters per division
• Seconds per division.
Range
The range varies depending on display type:
• For Log Magnitude display types: 1E-3 to 1E3
• For all other non-Smith display types: 1E-5 to 1E9
• For all Smith Chart display types, discrete values only: 3 | 0 | -10 | -20 | -30.
Default Value
1.000000E+001

:DISPlay:WINDow{1-16}:TRACe{1-16}:Y:PDIV2?
Description
The command enters the per-division scale value of the bottom display of the indicated channel and trace. It does not create an error if the command is invoked using a one-trace display, but, when a two-trace dis lay is re-invoked, all changes made to the “hidden” trace are discarded and the trace reverts to its prior visible settings. The query outputs the per-division scale value of the bottom display of the indicated channel and trace.
The command turns phase wrapping on/off on the indicated trace and channel. This is only used with rectangular graph trace displays. The query outputs the on/off status of Phase Wrapping on the indicated trace and channel.
