Dwell Time –The Dwell Time parameter progra
ms the period of
time that must elapse before the output amplitude hops to the next
amplitude setting. Dwell T
ime is associated with the Fixed Dwell
option only.
Marker Index – The marker index programs a step
in the hop data
string to output a pulse at the SYNC output connector. The SYNC
State button must be turned on to generate the hop marker output.
Frequency Hop
The Frequency Hop group contains parameters that control the
frequency hop function. These are: hop data, dwell control, dwell
time and marker position.
Hop Data – The hop data button in the frequency h
op group
provides access to the data string that controls the sequence of
frequency hops. The hop data table contains a list of frequencies
and the output will step from one frequency
level to another in the
same order as programmed in the hop data table.
To access the required parameter, click on the button below the
parameters sub-
group until the LED next to the required parameter
