Sweeping Rx1 & Rx2 at the same time & showing the Trace-Delta (needs dual Rx key)

The following mission allows you to sweep Rx1 and Rx2 at the same time at full speed showing the Clear/Write, AVG and MaxHold measurement traces of both inputs within a single view:

Dual Sweep Mission


In addition we added a spectrum ZOOM view and two Waterfall views where you can compare Rx1 and Rx2 within the Time Domain:

Full Sweep with Rx1 and Rx2


If you make any adjustments within one of the SPECTRAN V6 Sweep Zoom blocks please make sure to copy it 1:1 to the second SPECTRAN V6 Sweep Zoom block.

NOTE: For best operation it is crucial to keep the color adjustments of both Waterfall blocks identical. Use the "Save as User Default 1" feature which will save the setup to "Custom Preset 1". This setup can be then reloaded by any other block of same type e.g. the socond Waterfall block by just clicking to its "Custom Preset 1" button.

Hello, I have MIL EE and I'm trying the mentioned mission. However, I can only see the signal from Rx1, see the picture.

Did you press "Start" on the second sweep block?

Thank you, if there are separate IQ streams from Rx1 and Rx2 at the output, is it also possible to process (record) separately IQ data from Rx1 and Rx2? For example, store IQ from ISM 433 and 868MHz at the same time? Thanks for the info.

The data streams of Rx1 and Rx2 are separate, so you can record them separately of course. However there is only one receiver for them both, so you cannot use different center frequencies for Rx1 and Rx2 at the same time (this might change with the upcoming Spectran V6 ECO).

What you can do is one of the following:

  • Connect frequency-specific antennas to Rx1 and Rx2 respectively, and then sweep over a frequency range that covers both. Upside: No switching logic involved, Downside: a lot of measurement time is wasted on bands you are not interested in, and you need the outputs manually to only contain the requested bands.
  • Connect frequency-specific antennas to Rx1 and Rx2 respectively, and use the Receiver Band Sequencer to alternate between the two bands. Upside: You're only measuring stuff you're interested in, Downside: Additional complexity due to switch logic can make things more complicated and error-prone.
