Measurement Settings

Measurement Settings

Receive Instrument -Spctrum Analyzer Settings

Bandwidth-

Sets the bandwidth window on the

spectrum analyzer , the smaller the window the faster
the sweep. Format is in GHz.

Resolution-

Sets the Frequency Resolution of the

spectrum analyzer sweep. Inplut format is in MHz.

Trigger Mode-

Changes the way the power meter

reads the sensor, this setting is only applied to
certain meters.

Trigger Delay-

This sets the delay / Settling time

between when the Signal generator is called and the
power meter is queried for a reading. format is in
seconds. Example: 1/10 second = .10

Sweep Delay-

this sets the number of seconds the

signal generator will wait before initiating the sweep.
this allows larger antennas a chance to completely
stop moving.
