Function Commands
PEELing
NOTE This query returns the current offset value of the specified function only when the respective function display is
ON.
Returned Format [:FUNCtion<N>:OFFSet] <offset_value><NL>
Example 20 OUTPUT 707;":FUNCTION2:DISPLAY ON"
30 OUTPUT 707;":FUNCTION2:OFFSET?"
PEELing
Command :FUNCtion<N>:PEELing <operand>
Defines a function that applies TDR peeling to source 1 and places the result in the selected
function waveform. The TDR peeling is provided with Option 202, Enhanced Impedance and
S-Parameter software, and is used in TDR mode to analyze reflected signals at the source
and deconvolve the time domain reflections to create an impedance profile of the device
being tested. For differential and common mode responses, you must apply the TDR peeling
math function to the underlying individual responses and then sum or subtract the resulting
waveforms. TDR peeling can not be applied to TDT responses. TDR Peeling is only available
in TDR/TDT Mode.
Restrictions Available only in TDR/TDT mode. Software revision A.06.00 and above (86100C instru-
ments).
<operand> {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N>}
Example 10 OUTPUT 707;":FUNCTION1:PEELING CHANNEL1,WMEMORY1"
RANGe
Command :FUNCtion<N>:RANGe <full_scale_range>
This command defines the full scale vertical axis of the selected function. This automatically
changes the mode from auto to manual. <full_scale_range> is the full-scale vertical range.
Example This example sets the full scale range for function 1 to 400 mV.
10 OUTPUT 707;":FUNCTION1:RANGE 400E-3"
Query :FUNCtion<N>:RANGe?
This query returns the current full scale range setting of the specified function only when the
respective function display is ON.
Returned Format [:FUNCtion<N>:RANGe] <full_scale_range><NL>
Example 20 OUTPUT 707;":FUNCTION2:DISPLAY ON"
30 OUTPUT 707;":FUNCTION2:RANGE?"
SUBTract
Command :FUNCtion<N>:SUBTract <operand>,<operand>
This command defines a function that algebraically subtracts the second operand from the
first operand.
<operand> {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N> | <float_value>}
