TAS 200 Series Oscilloscopes
The Tektronix TAS 220 and TAS 250 oscilloscopes are dual-channel products
with frequency bandwidths of DC to 20 MHz and DC to 50 MHz respectively.
Both oscilloscopes feature a maximum sensitivity of 1 mV/division and a
maximum sweep speed of 10 ns/division.
In addition, the TAS 200 series oscilloscopes offer the following features:
High beam transmission and high intensity CRT displays for clear
waveforms at high sweep speeds.
High stability low-drift temperature compensation circuits to reduce baseline
and DC balance drift.
Trigger feature, Set to 50% that eliminates triggering adjustments when
displaying regular, video, and large duty-cycle-ratio signals.
Synchronization separator and trigger circuitry that permits the display of
TV signals. (You can automatically select vertical and horizontal signals
with the SEC/DIV control.)
Automatic focus (following an initial intensity adjustment).
