TAS 200 Series Oscilloscopes
The Tektronix TAS 220 and TAS 250 oscilloscopes are dual-channel products
withfrequencybandwidthsofDCto20MHzandDCto50MHzrespectively.
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:
H High beam transmission and high intensity CR T displays for clear
waveforms at high sweep speeds.
H High stability low-drift temperature compensation circuits to reduce baseline
and DC balance drift.
H Trigger feature, Set to 50% that eliminates triggering adjustments when
displaying regular, video, and large duty-cycle-ratio signals.
H 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.)
H Automatic focus (following an initial intensity adjustment).
