11-9 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 S
11
or S
21
measurements, set this to
Port 1. For S
22
or S
12
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)” on page 6-58. 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.
