# Name
Descriptions
10
Sweep Mode
When selected, allows setting an attenuation sweep with user defined start,
stop, step and dwell time values.
11
Hop Mode
When selected, allows setting a table of user defined attenuation and dwell
time which the attenuator will "hop" through.
12
Continuous
When selected, the attenuator will repeat the user defined sweep or hop until
the Stop button is clicked.
13
Duration
When selected the attenuator will repeat the user defined sweep or hop
sequence for the time specified (can be defined in milliseconds, seconds,
minutes or hours).
14
No. of Cycles
When selected the attenuator will repeat the user defined sweep or hop
sequence for the number of cycles specified.
15
High Speed
Enables high speed Sweep and Hop functions. See

16
PC control
Default setting. Sweep and Hop instructions are sent individually to the unit
See
section 3.4.2
17
Bidirectional
When selected, the attenuator will sweep or hop through the user defined
sequence, then repeat in the reverse direction (sweeping from stop to start or
hopping from last to first point in the hop list).
18
Start & Stop
Start and Stop the automatic run (Sweep or Hop) at the current attenuation
setting.
19

3.2.3
Log Attenuation Changes
It is possible to record all attenuation changes the unit undergoes by marking the “Log Att.
Changes” option (located at the lower left corner of the GUI).
Upon checking the option a pop-up will notify the user of the folder location the TXT log file will
be saved to “
C:\Users\Public\Mini-Circuits\ProgrammableAttenuator\Log\”.
The log file name
format will contain the current date and time, for example “
Log_
191211
153017
(in red the
current date
YYMMDD
and in blue the current time
HHMMSS
).
Once unchecked the log file will be saved properly with all the attenuation changes in the
aforementioned folder.
Note:
Trying to open the file while a recording is on-going will pop-up a notification alert about
the last attenuations possibly not being saved to the file.
