and right sides of the grid, respectively, in the lower right corner of the
pop-up Settings screen, click to eject the soft keyboard and enter the
frequency value through the soft
keyboard. Please pay attention to
the following points: The span and center frequency vary with the stop
frequency. The change of the span will affect other system
parameters. For more details, please refer to “Span”.
In Zero Span, the start frequency, stop frequency and center
frequency are always the same value. For more test examples, please

Calibration
Calibration and Normalization
The VNA Master is a field portable unit operating in the rigors of the
test environment. In order to ensure measurement accuracy, RF
calibration (SOLT) must be performed prior to making a measurement
in the field. Calibrating with the specified mechanical calibration
requires three calibration parts: open, short, and match(load) and one
RG316 RF cable. Calibration data is saved as user calibration data. It
can be saved to status 0/1/2/3/4, which will be automatically loaded at
the next boot and can be also be loaded via the RECALL menu.
The figure below shows the OPEN, SHORT, and LOAD calibration
components that are standard with the DeepVNA 101.
