Sweep.
The fully programmable HP 8116A features pulse as well as function generator capabilities in one small unit. A broad 1 mHz-50 MHz
band for all waveforms and a wide choice of operating and modulat-
ing modes assure high flexibility. These factors, plus good repeatabili-
ty, make the HP 8116A a sound, long-term investment.
HP's custom IC's have made it feasible to put the many HP 8116A
capabilities into such a small volume. Handling is simplified by a
unique, microprocessor-controlled, operating concept which ensures a
clear overview of the compact front panel at all times. When the mode
and waveform have been selected, illuminated labels show which pa-
rameters must be set. There's no clutter, no confusion.
Auto vernier. In normal mode, the HP 8116A's auto- vernier increments any desired parameter continuously until a stop signal is applied. This means that thresholds can be measured automatically,
without a controller.
Level or amplitude programming. The HP 8116A's output can be
programmed in terms of high and low levels or in terms of amplitude
and offset. Consequently a direct, automatic, conversion is always
feasible so that the HP 8116A can be programmed in the same terms
as the device is specified.
Safe limit. Devices can be protected by the limit feature. This prevents the output from exceeding a given magnitude.
For applications such as laser diodes or dc motors, square waves
can be programmed for constant duty cycles from 10% to 90%. For
digital test, or for simulating very low duty-cycle events, pulse width
can be programmed down to 10 ns. Square wave and Pulse modes
provide clean 6 ns edges that are ideal for many technologies. Pulse
width modulation and pulse recovery capability are available in Pulse
mode.
Sine and Triangle
10% to 90% duty cycle, programmable in 1% steps, provides ramps
and asymmetrical sine waves for testing VCO's, servos, amplifier linearity and industrial process control systems. Haverfunctions,
available in External Trigger, Gate and Burst modes, extend the applications to areas such as telephone line and vibration testing.
Modulation
All waveforms can be amplitude or frequency modulated. VCO operation allows frequency variation over two decades with an external
voltage; consequently transducer output can be conditioned for mag
tape recording, or frequency-shift keying or linear sweep can be carried out.
Option 001
10 1/2-decade log sweep. Sweep mode covers the wide 1 mHz - 50
MHz band in a single up sweep. Test setups require no more than an
X-Y recorder or scope because all necessary control signals are available. The HP 8116A sweeps can be internally triggered, if desired.
Accurate, counted bursts. A preprogrammed number of cycles of
any waveform can be generated in Burst mode. With sine, triangle
and square functions, bursts can be triggered internally as well as externally.
Hold capability. For material stress testing, low frequency functions
can be held at instantaneous levels. Hold is controlled by an external
signal.
for and
Powerful capability, small size and wide specified temperature
range make the HP 8116A a good choice for automatic test systems.
Also, the low cost means that it's now realistic to automate those routine bench jobs and leave more time for design. Comfortable software
features such as easy syntax and flexible format contribute to rapid
system design.
There's reliance in the HP 8116A's output because proper operation is always ensured by the instrument's error detector. This helps
the user to recover from an incorrect front panel or programming operation by indicating the offending parameter. Also, the built-in test
and diagnosis feature verifies correct function each time the instrument is switched on.
