Information
THE MODEL 175
The Model 175, Arbitrary Waveform Generator (Arb), generates
any waveform that can be expressed as a function of time.
The working Random Access Memory (RAM) has four sets of 256
addresses and each address accepts an 8 bit word. This
corresponds to a 1024 (time) by 255 (amplitude) matrix in
which to draw waveforms. These storage addresses can be
manually loaded by front panel controls or remotely loaded
via the GPIB interface. The stored waveform, or any portion
thereof, then can be generated at selectable clock rates and
amplitudes.
In addition to the four working Random Access Memories
(RAMs), four optional Programmable Read Only Memories
(PROMs) allow the same capacity for permanent waveform
storage. Sine, triangle, square and ramp waveforms are
always available.
Operation can be continuous or triggered. Triggering can be
for a preset number of cycles or the number of cycles
triggered can be monitored and displayed. Start and stop
addresses are selectable for partial waveform output. At low
frequencies, point-to-point smoothing can be selected to
minimize digital step size. Output may be held at any level,
or amplitude and offset can be slowly ramped to zero when a
ramp to zero command is given.
Front panel operation is by keyboard and display which gives
immediate verification of parameter and value in memory.
The Model 175 is fully compatible with the requirements of
IEEE Standard 488-1975 for integration into a General
Purpose Interface Bus (GPIB).
