PROTECTING YOUR INSTRUMENT
TURN OFF INSTRUMENT WHEN NOT IN USE
The lifetime of the switching elements in the pulse generator module is proportional to
the running time of the instrument. For this reason the prime power to the instrument
should be turned off when the instrument is not in use. In the case of failure, the
switching elements are easily replaced following the procedure described in a following
section.
DO NOT EXCEED 20 kHz
The output stage may be damaged if triggered by an external signal at a pulse
repetition frequency greater than 20 kHz.
The maximum duty cycle is 0.4%.
USE A 50
Ω
LOAD
A 50 Ohm load is
required
for proper operation. The output stage may be damaged if
the output is not terminated into a 50Ω load.
