Wide Frequency Range
Model 859 provides 0.5 Hz (2s periods) to 50 M Hz (0.02 με
periods), in a 5Va inch high, rack mountable instrument that
is fully programmable for systems applications.
Pulse widths can vary from 10 nanoseconds to 1 second,delays
to 1 second, transition times from 5 nanoseconds to 25
milliseconds, and output levels up to 20 volts. All pulse
parameters have a resolution of 3 digits. Extreme accuracy
and microprocessor assisted programming ensure that the
generator is producing exactly the pulse you
want without having to verify its output. Output may be one
pulse per period, double pulses or symmetrical square.
Pulses may also be complemented.
Operating modes include continuous, triggered, gated burst (1 to
10,000 pulse periods), external width mode to reconstruct or
shape an external signal, and unique time interval mode for
extremely long pulses.
Trigger status is always shown. Front panel annunciators
give positive indication of the selection of
manual triggering (pushbutton or GPIB), external rising or
falling edge triggering and of trigger presence.
Second Channel Option
Second channel output is available for dual pulse
