Setting Up a Repetitive Burst Signal

Setting Up Generic and Advanced Signals

Using the Remote Programming Interfaces

The following code performs the same tasks:

Protect the DUT //disconnect channels

:OUTP:CENT OFF

Set Up the Instrument //set mode to rBurst, 4, 4 :FUNC RBURST, 4, 4

//set freq to 100 MHz :FREQ 100 MHz

Set up Channel 1 //set signalmode to NRZ :DIG1:SIGN:FORM NRZ

//set delay to 50 ps :DEL1 50 ps

//set predefined levels to Custom values (Ampl=2V; Offset=0mV) :VOLT1:AMPL 2 V; :VOLT1:OFFS 0 mV

//enable output channel 1 :OUTP1:POS ON

//set datalength to 32 :DIG:PATT:LENG 32

//set pattern in channel 1

:DIG1:PATT #23211100000000000000000000000000000, DUAL

Generate the Signals //reconnect channels

:OUTP:CENT ON

// Prepare the trigger

//set trigger mode to Data :OUTP0:SOUR BITS

//set ampl to 1 V :VOLT0:AMPL 1 V

//set offset to 0 V :VOLT0:OFFSET 0 V

//enable trigger output :OUTP0 ON
