SWEep:STEP <#_steps>(?)
HS Syntax: 1603A<integer>(?)
Description
This programs the number of steps for the swept waveform. Program this parameter only if you fully
understand the effect on the waveform otherwise let the instrument determine the number of steps as
required to successfully complete the setting of the sweep.
Parameters
Name
Range
Type
Default
Description
<#_steps>
10 to
2000
Numeric
(integer only)
1e6
Programs the number of steps in a sweep. This number
affects the swept triangle and square only.
Response
The 3152B returns the current number of sweep steps value.
SWEep:MARKer<frequency>(?)
HS Syntax: 1613A<float>(?)
Description
This function programs marker frequency position. Sweep marker can be placed in between the start and the
stop frequencies. The marker pulse is output from the SYNC output connector.
Parameters
Name
Range
Type
Default
Description
<frequency>
10 to
100e6
Numeric
505e3
Programs the marker frequency position in units of Hz.
Response
The 3152B returns the current marker frequency value. The returned value will be in scientific notation(for
example: 100mHz would be returned as 100e-3 – positive numbers are unsigned).
FSK Modulation
Programming
Use the following commands for programming the FSK parameters.
FSK control is internal. The frequency will shift from carrier to shifted
frequency setting at a rate determined by the baud value and
controlled by a sequence of bits in the FSK data table. The
commands for programming the frequency shift keying function are
described below. Note that the carrier waveform frequency (CW)
setting is common to all modulation schemes.
FSK:FREQuency:SHIFted <shift_freq>(?)
HS Syntax: 0082A<float>(?)
Description
This programs the shifted frequency. The frequency shifts when the pointer in the data array points to “1”.
