The Model 801 is a 50 MHz general purpose laboratory pulse
generator. The instrument gives you full control in primary
pulse triggering and shaping plus simultaneous TTL, ECL, ECL
and sync pulses. The primary pulse output has
controllability in offset and independent rise/fall
durations, as well as pulse width, pulse delay and a choice
of positive, negative or complementary outputs. The TTL, ECL
and ECL are of fixed levels and rise times that are standard
for use with compatible devices. The primary pulse has
minimum rise and fall times of 7 ns and a maximum of 250 ms.
The output is ±20 volts with 50Ω source impedance which
provides ±10 volts into a 50Ω load. Upper and lower pulse
levels are fully adjustable through ±20 volts.
External triggering can be set to any point of the rising or
trailing edge of the trigger signal. Single pulses or pulse
pairs may be triggered; pulse width may be trigger
controlled; continuous pulses may be gated and a precise
number of pulses may be triggered for a ‘burst’ output.
Manual and external triggering is indicated by an LED on the
front panel for rapid visual set of trigger level.
