Performance Verification
The procedures in this section verify the performance specifications for the
WFM 601A, WFM 601E, and WFM 601M waveform monitors. Procedures that
apply to only one model indicate this limitation in their titles. Procedures without
such limits in their titles apply to all models. Where a procedure, such as Monitor
Out Gain Accuracy, differs greatly between models, different versions of the
procedure occur sequentially. Choose the one that pertains to the waveform
monitor under test. Test equipment used in this procedure should be operating
correctly and within calibration.
Perform the Performance Verification procedure at regular intervals to ensure
that instrument performance is within tolerance. The recommended interval for
performance verification is 2000 hours of operation or every 12 months.
For help on using the Tektronix TG2000/DVG1 generator recommended for this
procedure, refer to the information starting on page 5–9.
Equipment Required
The following equipment and accessory items are required to perform the
Performance Verification Procedure. Some test equipment is needed to test only a
specific model of waveform monitor. Such equipment dependency is included in
parentheses following the equipment name.
The equipment listed generally provides an accuracy ratio of 4:1 or better for
warranted measurement specifications. The equipment used in two procedures
provide a lesser accuracy ratio as follows:
H
(WFM 601A, WFM 601E only) Monitor Out Gain Accuracy is 1.5:1
H
(WFM 601A only) Audio Bandwidth is 1.5:1
The list includes the equipment specifications and recommended equipment that
meets these specifications. The procedures assume you are using the recom-
mended equipment. If you use other equipment, you will need to modify some
equipment set up and control settings.
1. Test Oscilloscope
Vertical Amplifier: 400 MHz Bandwidth, 2 mV sensitivity.
For example: Tektronix TDS540A Oscilloscope with TV Trigger option.
2. Oscilloscope Probe
For example: Tektronix P6101B X1 Passive Voltage Probe.
