Commands and Queries

- SV:WINDOW {KAISerbessel|RECTangular|HAMMing|HANNing|BLACkmanharris|FLATtop2}
- SV:WINDOW?

Sv ¶

The SV command tree.

Usage

Using the .query() method will send the SV? query.
Using the .verify(value) method will send the SV? query and raise an AssertionError if the returned value does not match value.

Properties

window: SvWindow

Return the SV:WINDOW command.

Description

This command sets or queries the window type used by the windowing function of the Spectrum View. The windowing function is a Fast Fourier Transform (FFT) technique used to minimize the discontinuities between successive frames of an RF time domain signal. The default window type is Blackman-Harris.

Usage

Using the .query() method will send the SV:WINDOW? query.
Using the .verify(value) method will send the SV:WINDOW? query and raise an AssertionError if the returned value does not match value.
Using the .write(value) method will send the SV:WINDOW value command.

SCPI Syntax

- SV:WINDOW {KAISerbessel|RECTangular|HAMMing|HANNing|BLACkmanharris|FLATtop2}
- SV:WINDOW?

Info

KAISerbessel specifies the Kaiser-Bessel window type (a high or moderate resolution window).
RECTangular specifies the Rectangular window type (a window function is equivalent to multiplying all gate data by one).
HAMMing specifies the Hamming window type (a high or moderate resolution window based on a cosine series).
HANNing specifies the Hanning window type (a high or moderate resolution window based on a cosine series).
BLACkmanharris specifies the Blackman-Harris window type (a low-resolution (high dynamic range) window based on a cosine series).
FLATtop2 specifies the Flattop2 window type (a low-resolution (high dynamic range) window).
