Specifications
The tables in this section list the specifications for the Tektronix WFM4000 and
WFM5000 Waveform Monitors. Items listed in the Performance Requirement
column are generally quantitative and can be tested by conducting the appropriate
Performance Verification procedure in this manual. Items listed in the Reference
Information column are useful operating parameters that have typical values;
information in this column is not guaranteed.
The specifications listed in the Electrical Specifications portion of these tables
apply over an ambient temperature range of +0 °C to +40 °C. The rated accuracies
are valid when the instrument is calibrated in an ambient temperature range of
+20 °C to +30 °C and has been operating continuously for at least 20 minutes
within this range.

Pulse-to-bar ratio 0.995:1 to 1.005:1 on

A sine-squared pulse near Nyquist is not
band-limited and so inherently has ringing
much larger than the waveform monitor
filter. A three term Blackman pulse with the
same HAD has much less inherent ringing,
so it is a better choice for most testing. See

In HD formats, the full screen picture is
downsampled to fit in 1024 x 768 size
In Low Frame Rate formats, frames are
repeated as needed to achieve XGA frame
rate; similar to 3:2 pulldown on some frame
rates
Pix Border On/Off Allows user to mask or show the inactive
portions of the raster such as ANC area for

When the border is on, the image is scaled to
correct the aspect ratio. When the border is
off, the image is either mapped pixel to pixel

reduce theartifacts
Synchronization Picture mode always uses internal timing; it
is not affected by external sync
