150 kHz HP
With this toggle key a 150 kHz highpass filter
can be switched into the measurement path.
This enables interference voltages in the
low-frequency range, e.g. from switch-mode
power supplies, to be suppressed. The
associated LED lights up when the filter is
active. This key is locked when the
"REMOTE" LED is lit.
(See also chapter 5 "Remote control")
LIMITER With this toggle key "LIMITER" the internal
protection diodes at the measurement output
"RF OUTPUT" can be turned off. The
protection diodes act as an input voltage
limiter (transient limiter) attached before the
"RF OUTPUT" output to protect
measurement equipment from high positive
and negative voltage spikes (>6 V). By
turning off the protection diodes higher
interference voltages can be measured.
The LED LIMITER "ON" lights up when the
protection diodes are active.
The default setting, e.g. after switching on, is
"ON".
The LIMITER function is only locally
switchable by means of the toggle key
"LIMITER".
When the protection diodes are turned
off, ensure that the connected
measurement devices cannot be
damaged by high voltage spikes.
