:CHANnel<N>:RANGe
Command
:CHANnel<N>:RANGe <range>
Description
The command defines the full-scale vertical axis of the selected channel.
The values represent the full-scale deflection factor of the vertical axis in
volts.
<N> An integer, 1-4 in a single digitizer system.
Range
40 mV to 400 mV
Example
:CHAN1:RANG 2.00000000000000E-01
Query
:CHANnel<N>: RANGe?
The query returns the current range value for the specified channel.
Returned Format
[:CHANnel<N>:RANGe] <range><NL>
:CHANnel<N>:DPRocessing:DDC:CFRequency
Command
:CHANnel<N>:DPRocessing:DDC:CFRequency
{<frequency_value>}
Description
The command sets the center frequency of the DDC for the specified
channel.
<N>
An integer, 1-4 in a single digitizer system.
<frequency_value>
A floating point value representing the center
frequency of the input signal. The valid range is from 0 to 1250 MHz in
steps of 250 MHz.
Query
:CHANnel<N>:DPRocessing:DDC:CFRequency?
The query returns the current center frequency of the DDC for the
specified channel.
Returned Format
[:CHANnel<N>:DPRocessing:DDC:CFRequency]
<frequency_value><NL>
NOTE
In modules with differential inputs, the query always returns
5.00000000000000E-0 and setting any value not equal to 0.5 results in
an error.
