The LIST:FREQuency command is used to clear the original sweep points and set
the frequencies of the sweep points. The LIST:FREQuency? query returns the
current frequency of each sweep point.
Command syntax: LIST:FREQuency<value>[,<value>*]
NOTE: * part means 201 sweep points at most can be set.
Where,
<value> is NR1, NR2 or NR3 data format.
<value> should be set from
20HZ-200KHZ(TH2829AX),
20HZ-300KHZ(TH2829A),
20HZ-500KHZ(TH2829B(BX)),
20HZ-1MHZ(TH2829C(CX)),
or return format will report errors.
For example: WrtCmd(“LIST:FREQ 1E3, 2E3, 3E3, 4E3”)
Set the frequency of the sweep point 1 as 1KHZ;
Set the frequency of the sweep point 2 as 2KHZ;
Set the frequency of the sweep point 3 as 3KHZ;
Set the frequency of the sweep point 4 as 4KHZ;
NOTE: HZ(hertz) is the suffix unit, MAHZ and MHZ is MHz (1E6 Hz).
Query syntax: LIST:FREQuency?
Return format: <NR3>, [,<NR3>*]<NL^END>
The LIST:VOLTage command is used to clear the original voltage of the each
sweep point and reset the voltage. The LIST:VOLTage? query returns the current
voltage of each sweep point.
Command syntax: LIST:VOLTage<value>[,<value>*]
