FRONT PANEL CONTROLS
1. POWER Switch
. This is the main power switch. When turning the instrument on,
there is normally a delay of 10 seconds before anything is shown on the main
display, as the internal operating system boots up.
If the main menu does not appear after 30 seconds, turn off the instrument and
leave it off for at least 60 seconds before applying power again.
2. OVERLOAD Indicator
. When the instrument is powered, this indicator is normally
green, indicating normal operation. If this indicator is yellow, an internal automatic
overload protection circuit has been tripped. If the unit is overloaded (by operating at
an exceedingly high duty cycle or by operating into a very low impedance), the
protective circuit will disable the output of the instrument and turn the indicator light
yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after
which the instrument will attempt to re-enable the output (i.e. light green) for
abOUT1 second. If the overload condition persists, the output will be disabled again
(i.e. light yellow) for another 5 seconds. If the overload condition has been removed,
the instrument will resume normal operation.
This overload indicator may flash yellow briefly at start-up. This is not a cause for
concern.
3. OUT1 CONNECTOR
. This BNC connector provides the 250V/5A (maximum) output
with 10 ns rise times. It is normally connected to the AVX-TEK3-TM1 output module
using a 12" / 30 cm length of RG-58 coaxial cable.
4. OUT2 CONNECTOR
. This SMA connector provides the 50V/1A (maximum) output
with 0.5 ns rise times. It is normally connected to the AVX-TEK3-TM2 or AVX-TEK3-
TM3 output modules using a 12" / 30 cm length of RG-316 coaxial cable.
