The 4
+
5 key allows you to incrementally subtract from the current value of a
parameter .
Pressing the 4
+
5 key will decrease the currently active parameter by the
increment value set with the 4
STEP SIZE
5 key . A parameter can be made
active by pressing its associated function key . F or example , pressing
the 4
FREQ
5 key will make frequency the active parameter , pressing the
4 POWER LEVEL 5 key will make output power level the active parameter , etc. If
no parameter is currently active , or the 4 SHIFT 5 , 4 ) 5 (ENTRY OFF) function
has been enabled, pressing the 4 + 5 key will have no eect.
If the 4 + 5 key is pressed and held down, the key will auto-repeat, that is , the
active parameter will automatically decrease rapidly in increment value steps .
Equivalent SCPI Commands
There is no equivalent SCPI command for the 4
+
5 key , however , the various
SCPI commands that send numeric parameter data include a \DO WN"
parameter option. Sending the \DO WN" parameter in place of the numeric
parameter is eectively the same as pressing the 4 + 5 key . F or example , if you
want to decrease the output frequency by its current increment value , send
the following command:
OUTPUT 719; "FREQ DOWN"
