The 9004 combines some most needed
Test Equipment in a very special way.
It effectively gives you a 1 Hz to 110
MHz generator & a 60W Power Supply
to power your test circuits. The
professional will find it covers a broad
spectrum of his test needs & the
schools will see plenty of experiments
with it. A very wide variety of
experiments in Analog, Digital & RF can
be performed with just this unit.

The unit is great for service or Test
bench & also simple enough for a
school lab. The touch of a button can
select the 5 digit counter to accurately
measure the Function Generator
frequency, the RF Generator Freq or an
External i/p signal. All functions are
kept completely independent for FULL
Functionality & there is no clutter of
switches & knobs.

The RF Generator covers a frequency
range all the way up to the commercial
FM band. It also has fixed internal AM &
FM modulation and also the facility of
External modulation.

The Function Generator features
Unipolar Square/Pulse outputs to
directly interface to digital circuits, in
addition to the standard Sine, Triangle,
and Square. There are 2 Outputs-50
Ohm & 600 Ohm to match audio
impedances.

The Model 9004 is

great for service or
Test bench & also
for school labs.

The touch of a

button can select
the 5 digit counter
to accurately
measure the
Function Generator
frequency, the RF
Generator Freq or
an External i/p
signal.
