LT584 programming notes

LT584 waveform template: [http://ohm.bu.edu/~hazen/CMS/template.txt template.txt]
read from instrument with "TEMPLATE?" command.

''''Initialization'''

Initialization sequence extracted from VB software ([http://ohm.bu.edu/~hazen/CMS/MainDAQ1.zip MainDAQ1.zip]

"Write" means to send a command and not expect a response.

"Query" means to send a command and read back a response.

* Write Device Clear (++clr), wait 1 seconds
* Write "*RST"
* Wait
* Query "*IDN?" and read identification string
* Write "WFSU SP,0,NP,500000,FP,0,SN,0" (Waveform setup:  send all data points, all segments)
* Write "TRSE EDGE,SR,C1" (Trigger setup:  edge trigger, channel 1
* Wait
* Write "TRDL 20PCT" (trigger delay: 20 percent)
* Write "C1:TRCP AC"  (trigger coupling)
* Write "C1:TRLV 0.01V" (trigger level)
* Write "C1:TRSL POS" (trigger slope)
* Wait
* Write "TRMD SINGLE" (single sweep mode)
* Wait
* Write "TDIV 1.0US" (horizontal scale)
* Wait
* Write "C1:TRA ON" (trace on)
* Write "C1:VDIV 0.1V" (vertical scale)
* Write "C1:ATTN 1" (1x attenuation)
* Write "C1:CPL A1M" (AC 1M coupling)
* Write "C1:OFST 0V" (no DC offset)
* Wait
* Write "SEQ ON,1000,500" (1000 segments of 500 points)
* (delay 500ms)
* Wait

The "Wait" operation can consist of sending the "*OPC?" command and waiting for the response (which should always be "1").

''''Arm for Trigger'''

* Write Device Clear (++clr)
* Write "ARM"

''''Check for Trigger'''

* Query "INR?" (wait for bit 13 [[8192]]

''''Read trigger times'''

* Query "C1:INSP? ''TRIGTIME'".  Returns list of times (try it to get the format).
