Tektronix 2230 Oscilloscope
Digital Storage Oscilloscope
The Tektronix 2230
Oscilloscope! is a combination nonstorage
and digital storage dual-channel 100 MHz bandwidth instrument.
It is a rugged, lightweight Oscilloscope
microprocessor operation and alphanumeric crt readout
of many of the front-panel controls. In the digital
storage mode, up to three waveform sets (CH 1 and/or CH 2)
may be stored in a SAVE REF memory and recalled for
display at a later time. The vertical system provides
calibrated deflection factors from 2 mV per division
to 5 V per division. The horizontal system provides
calibrated sweep speeds from 50 ns per division to 0.5 s
per division for nonstorage mode with three slower
sweep speeds (1 s, 2 s, and 5 s per division) added
for store mode operation. A X10 magnifier extends
the maximum sweep speed to 5 ns per division.
The digital storage sampling rate is 20 megasamples
per second maximum, and the acquired record length is
4K samples (1K may also be selected) for a single
channel or 2K samples for dual-channel (CHOP or ALT)
displays. Any contiguous 1K sample of an acquired record
is displayable. The fast sampling rate can capture a
glitch with a pulse width of at least 100 ns. A 4K
compress feature enables a 4K record length acquisition
to be compressed to 1K in length for ease in viewing or
storing in the SAVE REF memory. If compression is not
desired, all 4K or any 1K portion of a 4K record may be
stored in the SAVE REF memory. The SAVE store mode stops
the waveform acquisition in progress, allowing a particular
display to be stored or examined before further acquisitions
cause a waveform update.
Cursors may be used to obtain voltage measurements,
time difference measurements, and delay-time measurements
on any of the store mode waveform displays. Delta
volts, delay time, Delta
time, and 1/delta time (either
time or 1/delta time is selectable via the MENU)
are displayed in the crt readout for ease in obtaining
precise measurement results. The cursors are positioned
to any displayed store mode waveform to make measurements.
An alternate use of the cursor-positioning control is
to horizontally position the 1K display window to
any location within a 4K record length waveform
acquisition. The displayed portion of a 4K acquisition
is stored when the SAVE REF feature is used.
