Introduction
This performance check offers a means of rapidly checking
the operation of the Type 1A5. Only front-panel controls and
adjustments are referred to. Waveforms provided are repro ­
ductions of actual waveform photographs.
Recommended Equipment
The equipment listed here is recommended for use in
performance-checking the Type 1A5.
must meet or exceed the minimum requirements listed with
each item.
Items available through Tektronix Field Offices or Rep ­
resentatives are identified with a Tektronix Type or Part
Number.
All equipment used must be within calibration limits to
obtain valid results.
