All of these relate to the transmit characteristics of the radar and for these,
the archived value is displayed; users may not alter the fields. There are
other parameter fields that can be changed, identical to using ascope for
real-time data, such as the parameters to configure processing and plotting.
An example is the processing major mode and clutter filtering. The user
may freely select these while the RVP900 is in playback mode.
There are several ways to use ascope during RVP900 playback:
- The archive can be on the local RVP900.
- The archive can be on a separate archive host.
It does not matter where ascope is run, that is, either on the local RVP900
or on a networked host computer through DspExport.

Utility Settings
Network Note
In most cases, you are not sitting up at the radar, so you need to export the
displays for these utilities over the network. There are two ways to do this:
- Easy way: Use sigterm <hostname> to open a terminal window
- Manually: rlogin and export the display with
DISPLAY=<hostname>:0.0 (you may also need to type xhost + on
your local workstation)
It is often convenient to get the playback going in TS Archive with
"Repeat" set, then start ascope. Ascope starts up in the playback mode and
updates the display appropriately. You are free to select the data processing
and display parameters "on-the-fly" as playback is continuing and
repeating.
When ascope is set the way that you want it, you can use the TS Archive
menu to select different files and/or restart the playback.
