VXI 3002 manual Power-up options, Reverse power protection

STATUS BYTE

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)
Allowed suffices :	None
Default suffix :	None
:MEM	Set the memory location for a memory power up
Data type :	Decimal Numeric Program Data
Allowed suffices :	None
Default suffix :	None
Example:	POWUP:MODE MEMORY
	POWUP:MEM 172
POWUP?	Prepares message containing information on the instrument power up
	selection in the following format:
Example:	:POWUP:MODE MEMORY;MEM 135

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:
	<nr1>
	(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:
	<nr1>

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.
