To access the Sweep Menu, press the Sweep function hard key or press the Shift key then the
Sweep (3) key. All of the variables that affect the sweep can be found in this menu.
Run/Hold
Run Hold: Press this soft key to toggle the sweep to Run or Hold.
Sweep Type
Single Cont: Press this soft key to toggle the sweep type to Single or
Continuous. Single sweep sets the VNA Master to make a single sweep and
then wait for additional commands. The Continuous mode sweeps
continuously.
Data Points: Press this soft key to set the number of data points from
2to4001.
IFBW: Press this soft key to open a list box and set the Intermediate
Frequency bandwidth. The default is 10 kHz. Select 10 Hz for the maximum
dynamic range, and select 100 kHz for the maximum speed.
Sweep Averaging: Press this soft key to set the number of sweeps to use for
averaging. The minimum number is 1.
Configure Ports: Press this soft key to open the “Configure Ports Menu”.
Dithering
On Off: Press this soft key to toggle On and Off the Dithering function.
When a signal is dithered, a mathematical process removes the harmonics or
other undesirable distortions, and replaces these distortions with a constant,
fixed noise level. The result is a better representation of the signal.
RF Pwr in Hold
On Off: Press this soft key to toggle On and Off the condition of the RF
power transmitted from Port 1 and Port 2 when the instrument is put in Hold
mode. The RF power can be set either to stay on or to be turned off during
Hold. The default setting is for the RF to stay on during Hold, which helps to
stabilize the instrument temperature.
