x x xx
x
(Harmonic query) Returns the present instrument harmonic characteristic and location
of the fundamental output PRI (primary, the NORMAL terminals) or SEC (secondary,
the AUX terminals).
Response: <value>, PRI (harmonic value, fundamental at primary output)
<value>, SEC (harmonic value, fundamental at secondary output)
Example: HARMONIC? returns 5, SEC
Returns that the 5th harmonic frequency is selected, and the fundamental is at the
secondary output (AUX terminals). Therefore, the harmonic frequency appears at the
primary, or NORMAL terminals.

x
(Identification query) Returns instrument model number, serial number, and firmware
revision levels for the main, encoder, and inguard CPUs.
Responses: (Indefinite ASCII) A message containing four fields separated by commas
as follows:
1. Manufacturer
2. Model number
3. Serial number
4. Firmware revision levels for the Main CPU+Front Panel CPU+Inguard
PGA
Example: *IDN? returns FLUKE,5520A,5248000,1.2+1.3+1.3
Returns Fluke manufacturer, model 5520A, serial number 5248000, main firmware
version 1.2, encoder firmware 1.3, and inguard PGA 1.3.

xx xxx
(Increment command) Increments or decrements the output (as selected using the EDIT
command, or defaults to the primary output) and enters error mode; the same as using
the Calibrator output adjustment knob in local operation.
Parameters: <+ value> (increment value) (optional unit matching edit field)
<− value> (decrement value)
Example: INCR +.00001 mV
Load the error mode and increment the selected edit field by .00001 mV.
