Introduction

41-620 Three Channel and 51-620 Two Channel Function Generator Driver

The 41-620 and 51-620 are function generators with 3 (41-620) and 2 (51-620)

independent channels and with a common clock source. Each channel can generate

a signal up to 10 MHz with a maximum update rate of 80 MHz. Signal frequency and

amplitude are independently adjustable for each channel. Besides generating a sine,

triangle or square signal, an arbitrary pattern of a maximum of 256k samples can

be uploaded. Signal frequency can sweep with an adjustable step size. The

output signal can be AM modulated.

This instrument driver provides programming support for the PXI 41-620

Three Channel Function Generator and the PCI 51-620 Two Channel

Function Generator.

It contains functions for opening, configuring, taking measurements from, and

closing the instrument.

Assumptions:

To successfully use this module, the following conditions must be met:

- the card is fitted in a PCI slot or a connected PXI slot using one

of the following controller options:

Embedded controller

Suitable PCI-PXI extension system

- the logical address supplied to the initialize function must

match the logical address of the instrument

- for use in a LabViewRT system, the VISA driver option must be

selected during installation

Error and Status Information:

Each function in this instrument driver returns a status code that

either indicates success or describes an error or warning condition.

Your program should examine the status code from each call to an

instrument driver function to determine if an error occurred.

The meaning of the status codes can be found on the Function Return Value

page.
