:MATH:FILTer:W2
Syntax
:MATH:FILTer:W2 <freq2>
:MATH:FILTer:W2?
Description
Set or query the cutoff frequency 2 (ωc2) of the band pass/band stop filter. The default
unit is Hz.
Parameter
Name
Type
Range
Default
<freq2>
Real
Refer to Explanation
0.1 x screen sample rate
Explanation
When the type of the filter is set to BPASs (band pass) or BSTOP (band stop), you need
to set two cutoff frequencies. Send the :MATH:FILTer:W1 command to set cutoff
frequency 1 (ωc1); and send this command to set cutoff frequency 2 (ωc2). At this time,
the range of <freq2> is from (0.01 x screen sample rate) to (0.1 x screen sample rate),
with a step of (0.005 x screen sample rate). Wherein, Screen Sample Rate =
100/Horizontal Timebase.
Note: Cutoff frequency 2 (ωc2) must be greater than cutoff frequency 1 (ωc1).
Return
Format
The query returns current cutoff frequency 2 in scientific notation.
Example
:MATH:FILTer:W2 1500000 /*Set cutoff frequency 2 of the band pass filter to
1.5MHz*/
:MATH:FILTer:W2? /*The query returns 1.500000e+06*/

:MATH:OPTion:STARt
Syntax
:MATH:OPTion:STARt <sta>
:MATH:OPTion:STARt?
Description
Set or query the start point of the waveform math operation.
Parameter

Default
<sta>
Integer
0 to (End point currently set - 1)
0
Explanation
 This command is invalid for the FFT operation. Sending this command will modify the
start points of all the operations (except FFT).
 The source selected is equally divided into 1200 parts horizontally, in which the
leftmost is 0 and the rightmost is 1199.
Return
Format
The query returns an integer.
Example
:MATH:OPTion:STARt 50 /*Set the waveform start point to 50*/
:MATH:OPTion:STARt? /*The query returns 50*/

Command
:MATH:OPTion:END
