HPG™ 13150 400 V RF Power Generator
Prerelease version
To Adjust the Tune and Load Capacitors Using the HPG Generator Front Panel:
Use the four capacitor keys on the HPG generator front panel to adjust the
tune and load capacitor positions (see
). When you press one of
these keys, the associated variable capacitor will turn in the chosen direction.
The actual capacitor position will flash on the front panel display.
Note:
Improper use of this feature may cause the Variomatch unit to search
but fail to tune or to exhibit modulated power delivery. These conditions
are characterized by nonstable plasma glow or flickering plasma. See
“Troubleshooting Guide” on page 6-2
for more detailed information.
UNDERSTANDING ADDITIONAL OPERATING
FUNCTIONS
Using the Pulsing Function
The HPG generator’s pulse function allows you to switch on the RF power (at
a given set point) and switch it off with the pulse frequency. You may select
between:
•
Internal pulsing
Internal pulsing modifies the
pulse repetition frequency
(PRF). The
waveform is always a rectangle; the power is given by the set point. The
internal pulse generator is configurable for pulse frequencies between
1 Hz and 30 kHz and duty cycles between 1% and 99%.
