25-PIN USER PORT ELECTRICAL CHARACTERISTICS
Analog Inputs
By default, the User port set point and DC bias input signals (pins 5 and 7)
are scaled 0 V to 10 V. These signals are scalable from 0 V to 2V up to 0 V to
10 V in increments of 0.5 V. You can set the scaling through the
RS-232 port
24 11 INTERLOCK
SATISFIED Digital
output When the interlock is
satisfied, a low (opto-coupler
output) impedance is created
between this pin and return
pin 11 (8 mA maximum).
For a wiring diagram, see
Figure 4-14 on page 4-20 .
25 19 BLANKING/
PULSING Pulse
input
When Pulse Settings is set
to External , this pin allows
you to pulse (blank) the RF
power. Set the required logic
for RF on and off through the
front panel menu (see
“Changing the Pulse Input
Configuration Settings” on
page 5-32
).
When Pulse Settings is set
to Internal , this pin allows you
to switch between internal
pulsing and continuous wave
operation. Select the
appropriate function and
signal level in the Pulse Input
Configuration in the front
panel menu.
For a wiring diagram, see
Figure 4-15 on page 4-21 .
