Usage
Conditions


All functions




Set or query an input filter.


Syntax


(Command)
(Query)


:UNIT:FILTer CH$,A
:UNIT:FILTer? CH$

(Response)

CH$,A$
CH$:CH1 to CH4
A<NR1>:0 (=OFF), 5, 50, 500, 5000, 50000


Details


Sets the filter for channel CH$.
Returns the current filter setting for channel CH$.

The filter is OFF when argument A = 0.

All functions




Set or query the module mode.


Syntax


(Command)
(Query)


:UNIT:MODE CH$,A$
:UNIT:MODE? CH$

(Response)

CH$,A$
CH$:CH1 to CH4
A$:DC, RMS


Details


Sets the measurement mode of the module hosting channel CH$.
Returns the current measurement mode setting of the module hosting channel CH$ as a text string.

DC  Measure the instantaneous waveform.
RMS  Measure the RMS waveform.


Example


:UNIT:MODE CH1,DC
:UNIT:MODE? CH1
(Response)  :UNIT:MODE CH1,DC  (when headers are enabled)


Note


When voltage drop trigger or waveform detection trigger is selected, RMS cannot be set.


Usage
Conditions


All functions




Set or query input channel zero position.


Syntax


(Command)
(Query)


:UNIT:POSItion CH$,A
:UNIT:POSItion? CH$

(Response)

CH$,A<NR1>
CH$:CH1 to CH4
A<NR1>:Position point(%)


Details


Select Hold or Return in the module hosting CH$.
Query Hold or Return in the module hosting CH$.


Example


:UNIT:POSItion CH1,50
:UNIT:POSItion? CH1
(Response)  :UNIT:POSITION CH1,50  (when headers are enabled)


Note


The effect of argument A depends on the display amplitude magnification factor.


Usage
Conditions


All functions




Set or query Query Input Voltage Range.


Syntax


(Command)
(Query)


:UNIT:RANGe CH$,A
:UNIT:RANGe? CH$

(Response)

CH$,A<NR3>
CH$:CH1 to CH4
A<NR3>:Range(V)


Details
