T200S Specific Commands

[SOURce]:FREQuency:SWEep:STARt?

Description

This query indicates either the current or the

minimum/maximum/default start frequency of a swept signal.
At *RST, this value is set to MINimum.

Syntax

[:SOURce]:FREQuency:SWEep:STARt?<wsp>

[MAXimum|MINimum|DEFault]

Parameter(s)

MAXimum

The query returns the maximum possible start frequency for

the laser model.

MINimum

The query returns the minimum possible start frequency for

the laser model.

DEFault

The query returns the default start frequency for the laser

model.

Response Syntax

<start>

Response(s)

start:

Floating point number in Hz corresponding to the current start

frequency or the minimum/maximum/default start frequency,

depending on the specified query parameters.

Example(s)

SOUR:FREQ:SWE:STAR 197.5 THZ
SOUR:FREQ:SWE:STAR? returns 1.014
