HARMONIC

xx xx x
(Harmonic command) Makes the frequency of one output a multiple of another output
for the ac voltage or ac power functions (sine waves only). For example, in dual ac
voltage, have the frequency of the voltage output on the Calibrator front panel NORMAL
terminals at 60 Hz and the frequency of the voltage output on the AUX terminals at the
7th harmonic (420 Hz). The range for the harmonics is 1 to 50.
Parameters: <value>, PRI (fundamental at 5522A NORMAL terminals)
<value>, SEC (fundamental at 5522A AUX terminals)
Example: HARMONIC 5, PRI
Load the fundamental frequency at the primary (PRI) output (NORMAL terminals), and
the 5th harmonic frequency is at the secondary output (AUX terminals). For example, if
the fundamental frequency output is 60 Hz, the harmonic frequency output is 300 Hz.

(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.

(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,5522A,5248000,1.0+1.3+1.8
Returns Fluke manufacturer, model 5522A, serial number 5248000, main firmware
version 1.0, encoder firmware 1.3, and inguard PGA 1.8.
INCR

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
