SWEep:FREQuency:STOP <stop_freq>(?)
HS Syntax: 1611A<float>(?)
Description
This specifies the sweep stop frequency. The 3152B normally sweeps from the start to the stop frequency,
however, if the sweep direction is reversed, the 3152B will sweep from the stop to the start frequency. The
start and stop frequencies may be programmed freely throughout the frequency range of the instrument.
Parameters

Description
<stop_freq>
10e-3 to
100e6
Numeric
1e6
Programs the sweep stop frequency. Sweep stop is
programmed in units of Hz.
Response
The 3152B returns the current sweep stop frequency value.
SWEep:FREQuency:RASTer <sclk_freq>(?)
HS Syntax: 1612A<float>(?)
Description
This programs the sample clock frequency for the swept waveform. Program this parameter only if you fully
understand the effect on the waveform otherwise let the instrument determine the sample clock setting as
required to successfully complete the setting of the sweep.
Parameters
Name

Type
Default
Description
<sclk_freq>
10e-3 to
250e6
Numeric
1e6
Programs the sample clock frequency in units of
samples per second.
Response
The 3152B returns the current sweep sample clock frequency value.
SWEep:FUNCtion {SINusoid|TRIangle|SQUare}(?)
HS Syntax: 1604A<1|2|3>(?)
Description
This specifies the swept function. There are three functions that can be swept: Sine, Triangle and Square.
The sine sweep is generated by the DDS but the triangle and the square are computed and placed into
arbitrary waveform memory in segments and re-played as a sequenced waveform.
Parameters
Name
Type
Default
Description
SINusoid
Discrete
SIN
Selects sine as the swept waveform
TRIangle
Discrete
Selects triangle as the swept waveform
SQUare
Discrete
Selects square as the swept waveform
Response
The 3152B returns SIN, TRI, or SQU depending on the selected waveform setting.
