Tektronix 2465B Operator's Manual

Applications
Period and Frequency
Using Parametric Measurements
To measure Period and Frequency using the Parametric
Measurement feature:
1. Push the MEASURE button.
2. Select FREQUENCY from the menu.
The oscilloscope automatically scales the amplitude and timing for the
best measurement. Parametric measurements can only be done on repetitive
signals. Signals with multiple valid trigger points will give erroneous results if
measured with parametric measurements.
Using the Counter/Timer/Trigger (CTT)
1. Push the MEASURE button.
2. Select COUNTER from the menu.
3. Select FREQuency from the menu.
Without Parametric Measurements or CTT
1. Set SEC/DIV and, if necessary, X10 MAG to spread one cycle over as
wide a span as possible.
2. Turn on At or 1 /At and align the cursors with identical, fast-slewing
points on consecutive cycles, such as zero-crossings.
