GPIB Control
This tests the integrity of the waveform memory. The waveform
memory stores the waveforms that are being generated at the output
connector and therefore, flaws in the memory can cause distortions
and impurity of the output waveforms. Each channel has its own
working memory and therefore each channel is tested separately.
Equipment: Distortion Analyzer, ArbConnection
Preparation:
1.
Connect 2074 Channel outputs to the distortion analyzer
input. Configure the 2074 as follows:
SCLK:
Waveform:
Amplitude:
Output:
2.
Using ArbConnection prepare and download the following
waveform:
Wavelength:
Waveform:
SCLK
Test Procedure
1.
Perform Sine wave distortion. It should be less than 0.1 %
Pass
This tests the communication with the 2074 using the various interface
options. Connecting and setting up the 2074 for operation with the
various interface options is described in Chapter 2. Before you
proceed with and of the following tests, make sure first that the 2074 is
configured to operate with the selected test. GPIB operation requires
setting of the GPIB address, LAN operation requires correct setting of
the LAN parameters and USB operation requires that the USB port is
configured correctly and USB driver installed on the host computer.
Equipment: Distortion Analyzer, ArbConnection
Preparation:
1.
Set up the 2074 for GPIB operation and connect the instrument
to a host controller
