the dwell time is shorter than the period of the waveform. For example, if you program dwell time of 1ms and
the amplitude step has frequency of 1Hz (1s period), the amplitude step will last 1 second although the dwell
time is 1ms.

In the above example, the first number is the amplitude value and the second number is its dwell time.
Therefore, only even number of sets can be located in this table.

Description
<var_hop_data>
Double
Block of binary data that contains information of
amplitude hop values and their respective dwell time.
AHOP:MARKer <index>(?)
HS Syntax: 0060A<integer>(?)
Description
Programs where on the amplitude list the 3152B will generate a pulse, designated as Hop marker, or index
point. The marker pulse is generated at the SYNC output connector.

Description
<index>
1 to 5000 Numeric
(integer only)
1
Programs a marker pulse at an index amplitude hop
position.
Response
The 3152B returns the current marker position.
3D Modulation
Programming
Use the following commands for programming the 3D modulation
parameters. 3D modulation requires an external utility to download the
modulation coordinates into the 3D memory location. In case you
intend to build your own 3D profiles, use the examples as given in the
IVI drivers that are supplied with the 3152B.
The commands for programming the 3D function are described below.
Note that the carrier waveform frequency (CW) setting is common to
all modulation schemes.
3D:DATA <data_array>

Description
<data_array>
Double
Block of binary data that contains information on the 3D
profile. Data contains amplitude sweeps for both
channels as well as frequency and phase sweep
parameters for the 3D waveform.
