Appendix 1.1 Commands
• Select mode (OFD2) is validated when the OF
command is executed if “m” is set to “0”
(default for normal measurement) or “1”
(default for integration).
• If you select default for normal measurement,
the output of channel 13 is the information on
the frequency target function that is currently
measured, and the output of channel 14 is the
information displayed on display C. If you
change either the frequency measurement target
or display information of display C, the output
also changes.
OH/OH? Sets communication output information
types in case of harmonic analysis/
inquires about the current settings.
Syntax OH m1,m2 <terminator>
“m1” indicates output type no.

2 :Element 2 (for model 253503 only)
3 :Element 3 (for WT130 only)
Query OH? <terminator>
Example OH13,1
Description • Parameter error 12 will occur if “m1” or “m2” is
set to an illegal value.
OR/OR? Designates the harmonic order of the
harmonic component shown on display B
(V,A,W,V %, A%, W%, V deg, A deg)/
inquires about the current settings.
Syntax OR m <terminator>
“m” indicates the harmonic order
m= any number between 1 to 50 (or 30)
Query OR? <terminator>
Example OR50
Description • Parameter error 12 will occur if “m” is set to an
illegal value.
• Depending on the fundamental frequency of the
PLL source set as the input, the maximum
number of orders varies.
• When an order exceeding the maximum has
been set, display B will show [——].
OS Requests output of setting parameters via
communications.
