Switching on the VNA
When the VNA is powered on, the front-panel channel activity indicators will flash to indicate that the
controller has started correctly.

Calibration kit parameters
The minimum requirements to carry out a 12-term calibration (full error correction) depend on the device to
be tested. For example, the most accurate calibration is for ‘insertable’ devices, and this requires a total of
six standards: three of the four in each of the male and female cal standards.
An ‘insertable’ device is one that has connectors of different sexes at its ports. On the other hand, a
calibration for a non-insertable device can be carried out using only three standards by using the “unknown
through” calibration method.
The calibration kits parameters can be inspected using the
Calibration Kit Parameters
window (see below)
found under the
Tools
menu. From this the kit editor can be launched to modify and create new kits as
discussed later in the section.
The ‘unknown thru’ calibration method only requires that the ‘thru’ adaptor be reciprocal: that is, have S
