1.3.6 Return Function
A front panel pushbutton or external signal will cause
the output to ramp back to the start value. The rate of
this ramp is adjustable from 0 (instant return tostart) to
100 ms per vertical point.
1.3.7 Stored Waveforms
Three additional waveforms may be stored (with their
parameter settings) in waveform memory. These may
later be recalled into, or exchanged with the active
waveform. This feature is only available with horizontal
resolutions of 2048 points or less.
1.3.8 Nonvolatile Instrument Setup
The complete instrument setup is stored in battery
backed up memory so that it will not have to be reset
after the power has been turned off.
1.3.9 Series Operation
Several Model 75's can be connected in series, each one
producing a burst of waveforms, with their outputs
summed together (using the "sum in" connector). This
can be used to produce long waveforms or unusual
sequences such as 50 "normal" waveforms and then
1 "abnormal" waveform.
1.3.1 0 Parallel Operation
Several Model 75's can be connected in parallel to create
phase coherent arbitrary waveforms. The phase relation-
ship is completely adjustable with a resolution equal to
the horizontal resolution of the waveform. This feature
is useful in three axis mechanical testing and multi-phase
power applications.
1.3.1 1 Communications Options
Either an IEEE-488or RS232Ccommunication interface
is available to transfer waveform data and control the
Model 75 from a computer.
1.4 SPECIFICATIONS
1.4.1 Standard Waveforms
DC, square, triangle, up-ramp, down-ramp, sine, cosine,
inverse sine, and haversine waveforms are provided.
Each of these waveforms can be stored into the
waveform memory between thumbtacks automatically,
and then edited with the waveform editing functions if
desired.
1.4.2 Operational Modes
Continuous
Output runs repetitively from the programmed start
address to the programmed stop address.
Triggered
Output quiescent until triggered by external signal or
front panel pushbutton, then runs until another break
point is encountered. Break points can be inserted
anywhere in the waveform with the default break point
at the beginning of the waveform.
Gated
Same as triggered mode except that the output is con-
tinuous for the duration of the gate signal and until the
first break point encountered after the gate signal ends.
Burst
Same as in the triggered mode except that a program-
mable number of waveforms is counted before the
waveforms stop. The maximum burst is 1,048,575
waveforms.
Toggled
The output is quiescent until triggered. It then runs con-
tinuously until another trigger stops the waveform at the
next break point.
1.4.3 Waveform Resolution
Normal Waveform
2048 points horizontal
x
4095 points vertical.
Chained Waveform
81 92 points horizontal
x
4095 points vertical. Stored
waveforms are not available with chained operation.
1.4.4 Sample Rate
Range
0.02 Hz to 2.0 MHz (50 s to 500 ns)
Waveform Period and Frequency
The actual waveform period is the number of horizontal
points (from start to stop address) times the sample time.
This can range from 1 microsecond for a square wave
to 11 3.8 hours for a waveform using all 81 92 points.
Frequency Resolution
