4. Enable the ECLTrg0 Line
[SOURce:]MARKer:ECLTrg0[:STATe] ON
This enables the marker output on the ECLTrg0 trigger line.
(Although
*RST automatically enables the AFG for marker outputs, it
is given here for good programming practice.)
5. Select the Master AFG’s ECLTrg1 Feed Trigger Source
[SOURce:]MARKer:ECLTrg1:FEED <source>
“ARM:STARt:LAYer2”
This source outputs a marker pulse when the master’s waveform
output starts. The marker is output on the ECLTrg1 trigger line.
6. Enable the ECLTrg1 Line
[SOURce:]MARKer:ECLTrg1[:STATe] ON
This enables the arm output on the ECLTrg1 trigger line.
7. Select the Servant AFG’s Reference Oscillator Source
[SOURce:]ROSCillator:SOURce ECLTrg<n>
[SOURce:]ROSCillator:FREQuency:EXTernal 40M
This command selects the Reference Oscillator Source. To
synchronize the servant AFG with the master, select the ECLTrg0
trigger line. (The ECLTRG0 line is a 40 MHz clock.)
8. Select the Servant AFG’s Sample Source
TRIGger[:STARt|:SEQuence[1]]:SOURce INT2
Select the Divide-by-n time base for the sample source.
9. Setup the Servant AFG For a 5 V Square Wave Output
[SOURce:]FREQuency[1]:FIXed <frequency>
[SOURce:]FUNCtion[:SHAPe] SQUare
10. Setup the Servant AFG Arm Source to be the ECLTrg1 Line
ARM[:STARt]:LAYer2:SOURce ECLTrg1
This command tells the servant AFG to start on the arm signal from
the master AFG.
11. Generate the Servant AFG’s Output
INITiate[:IMMediate]
12. Wait for the Servant AFG to Complete its Setup
STATus:OPC:INITiate OFF;*OPC?
13. Generate the Master AFG’s Output
INITiate[:IMMediate]
