GPIB Operation

KJM6335

4.6

Sample Program

The following demonstrates a sample program in which the
KJM6335 is GPIB-controlled, using Microsoft Visual Basic via a
National Instruments GPIB board meeting NI-488.2 specifications.
The program sets up each item, then displays a jitter value and
judgment result once.

'----------------------------------------------------

Dim rd As Integer
Call ibfind("DEV2", rd)

'Opens GPIB device.

Call ibconfig(rd, 6, 1)

'Sets device configuration (enable
'repetition of addressing).

'Model information acquisition [company name, model, and version number]
'----------------------------------------------------

Call ibwrt(rd, "*IDN?")

'Sends model information acquisition
'message.

Dim strModelInfo As String
strModelInfo = Space(128)
Call ibrd(rd, strModelInfo)

'Reads out model information and stores it
'to a variable.

MsgBox Left(strModelInfo, ibcntl)

'Front panel setup
'----------------------------------------------------

Call ibwrt(rd, "TIM:CON 0.3")

'Sets TIME CONST to 0.3s

Call ibwrt(rd, "SYM:MOD AUT")

'Sets SYMMETRY mode to AUTO

Call ibwrt(rd, "DEL:MOD AUT")

'Sets DELAY mode to AUTO

Call ibwrt(rd, "RF:TRIG:EDG POS")
