Vector Network Analyzer Measurement Guide : Vector Voltmeter, Option 15 : Vector Voltmeter Menus
 
Vector Voltmeter Menus
In the Vector Voltmeter mode, the function hard keys display the following labels: “CW”, “Table”, “Save/Recall”, and “Cal”. The fifth function hard key has no function in the Vector Voltmeter mode.

CW Menu
CW Frequency
Press this soft key to set the desired measurement frequency. Enter the desired frequency using the keypad, the arrow keys, or the rotary knob. If entering a frequency using the keypad, then the soft key labels change to GHz, MHz, kHz, and Hz. Press the appropriate units key. Pressing the Enter key has the same affect as using the MHz soft key.
Measurement Type
Return Insertion
Press this soft key to toggle between Return and Insertion measurements. When Return is selected, the Return Meas Format soft key is displayed.
Return Meas Format
dB VSWR Imped
Press this soft key to toggle among dB, VSWR, and Imped (impedance) measurements formats. This setting is relevant (and the soft key is displayed) only when the Measurement Type soft key is set to Return.
Save New Reference
Press this soft key to save the current measurement as the reference measurement. Entering a reference puts the Vector Voltmeter in relative measurement mode.
Clear Reference
Press this soft key to remove the reference measurement from memory. The Vector Voltmeter exits the relative measurement mode.
Cal Port
Port_1 Port_2
Press this soft key to set the transmission port for subsequent measurements. For making S11 or S21 measurements, set this to Port 1. For S22 or S12 measurements, set this to Port 2. This soft key is displayed only with the MS20xxC VNA Master and is not relevant to the MS20xxB VNA Master.
Source Power
Press this soft key to open the Source Power Menu (MS20xxB and S412E only). The Source Power menu in VVM mode is the same as in VNA mode.
IFBW
Press this soft key to open a list box and set the Intermediate Frequency bandwidth. The default is 10 kHz for the MS20xxC series instruments and 1 kHz for the MS20xxB and S412E series instruments. Select 10 Hz for the maximum dynamic range; select 100 kHz for the maximum speed.
 
Continuous Wave (CW) Measurements
In Continuous Wave, the meter displays the selected frequency and indicates if calibration is On or Off for that specific frequency. The instrument must be calibrated for each chosen frequency.
The return measurement format units are displayed near the center of the Vector Voltmeter window. For dB format, the units are dB and deg (degrees). For VSWR format, the voltage standing wave ratio values are unitless. For Imped (impedance) format, the units are Ohms and jOhms.
The measurement type and format are displayed at the bottom of the Vector Voltmeter window.

Select Cable
Press this soft key to open the Select Cable List Box.
One of the twelve cable numbers is underlined to indicate which cable is selected. Change to a different cable by pressing the Select Cable soft key. The data for the selected cable is highlighted in that cable row within the displayed table.
Save New Reference
Press this soft key to save the current measurement as the reference measurement. Entering a reference puts the Vector Voltmeter in relative measurement mode.
Clear Reference
Press this soft key to remove the reference measurement from memory. The Vector Voltmeter exits the relative measurement mode.

Save/Recall Menu
‘Pressing the Save/Recall function hard key opens the File menu. For a description of the soft keys in the File menu, refer to the file management instructions in the user guide for your instrument.
Calibration Menu
For descriptions of the Calibration menu items and options, refer to Calibration Menu. The Calibration menu in Figure: File and Calibration Menus is from the MS20xxC VNA Master.
