[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry
Syntax
[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry <val>
[:SOURce[<n>]]:FUNCtion:RAMP:SYMMetry?
Description
Sets or queries the symmetry of the Ramp waveforms output from the specified
function/arbitrary waveform generator channel.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
{1|2}
When omitted, by default, the
operations are carried out on GI.
<val>
Real
0 to 100
10
Remarks
Symmetry is defined as the percentage that the rising period of the ramp takes up in
the whole period.
T
t
Symmetry=t/T*100%
Return
Format
The query returns the current symmetry in scientific notation.
Example
:FUNCtion:RAMP:SYMMetry 50 /*Sets the symmetry of Ramp waveform output
from GI to 50%.*/
:FUNCtion:RAMP:SYMMetry? /*The query returns 5.000000E+1.*/
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]
Syntax
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]?
Description
Sets or query the amplitude of the signal output from the specified function/arbitrary
waveform generator channel. By default, the unit is Vpp.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
{1|2}
When omitted, by default,
the operations are carried
out on GI.
<amplitude>
Real
Related to the current
output impedance
HighZ: 20 mVpp to 5
Vpp
50Ω: 10 mVpp to 2.5
Vpp
5 Vpp
Remarks
Send the [:SOURce[<n>]]:OUTPut[<n>]:IMPedance command to set the input
impedance.
Return
Format
The query returns the amplitude value in scientific notation.
Example
:VOLTage 2 /*Sets the output amplitude of GI to 2 V.*/
:VOLTage? /*The query returns 2.0000000E0.*/
