The two-channel Tektronix 2225 analog Oscilloscope
contains features usually found in more expensive instruments. The
low-noise vertical system operates at 500 MicroV/div. You also get
horizontal alternate sweep magnifications of X5, X10, and X50. These
allow you to perform most measurements typically associated with dual
time base scopes. The unit provides the convenience of Tek "hands-free"
triggering, including HF and LF reject trigger filtering, TV line and
field triggering. The single-sweep function is very useful for
babysitting waveforms and waveform photography. The unit has a
bandwidth of 50 MHz with a risetime of 7.0 ns; 40MHz with a risetime of
8.8 ns., -3 dB; p-p auto triggering. 0.5 s/div to 0.05 Micros/div, max of 5
ns/div.
