Power-up options
These commands allow you to select between powering up with the factory settings (given in Table
3-1) or with the settings of your choice stored in one of the full memory locations (range 100 to
199) or carrier frequency memory locations (range 0 to 99).
POWUP
[not used alone]
:MODE
Select the power up mode. The instrument can power up in either the
factory preset mode or from a selected memory
Data type : Character program data (FACTORY or MEMORY)

Reverse power protection
Accidental application of power to the RF OUT socket trips the reverse power protection circuit.
The following commands enable you to detect when the protection circuit has been tripped, reset
the protection (after you have removed the source from the socket), and find out how many times
the circuit has tripped.
RPP
Reset reverse power protection trip (short form)
:RESET
Reset RPP trip
Data type : None
Allowed suffices : None
Default suffix : None
Example: RPP:RESET
RPP:TRIPPED?
Prepares message containing information on whether the RPP circuit is
currently tripped in the following format:
(0 = not tripped, 1 = tripped)
Example: 1
RPP:COUNT?
Prepares message containing information on the number of times the
RPP circuit has tripped in the following format:
Example: 3
Note that the protection circuit may be activated when the generator is set to a high level and the
RF OUT socket has no terminating load.
