How to use the Rohde & Schwarz FPL1000's Sequencer as a workaround to require only a single trigger to initiate 101 sweep counts (for trace averaging or max hold).
1. Configure 2 spectrum channels:
a. Run Continuous, Sweep Count = 0, Trigger = Ext Trigger 1
b. Run Single, Sweep Count = 101, Trigger = Free Run, Trace 1 Mode = Max Hold
2. Enable the Sequencer in Continuous Sequence mode
3. Send one TTL trigger to the FPL. This will execute one sweep on the 1st spectrum channel, then the sequencer will immediately jump to the 2nd spectrum channel, complete 101 sweeps as fast as it can, then stop.
4. Export the max hold trace on the 2nd spectrum channel to a CSV file.
