5.8.6 Charging amplifier
C-70xx supports the DSUB-Q2 charge amplifier, which is a 2-chanel pre-amp in the shape of an imc
terminal connector enabling connection of two charge sensors via BNC.
The charge amplifier is recognized and adjusted automatically if either DC- or AC charge coupling is
selected in the amplifier dialog. In order for these two coupling types to be displayed for the channel
selected, the charge amplifier must be read by means of TEDS technology or it must be adjusted
according to an appropriate sensor database entry.
Find here the description of the DSUB-Q2.
5.8.7 Sensor supply module
C-70xx channels are enhanced with a sensor supply unit, which provides an adjustable supply voltage for
active sensors. The reference potential, in other words the sensor's supply ground contact, is the
terminal GND.
The supply voltage can only be set for a group of eight channels.
The supply outputs are electronically protected internally against short circuiting to ground. The
reference potential, in other words the sensor's supply ground contact, is the terminal GND.
The supply voltage can only be set for all measurement inputs in common. The voltage selected is also
the supply for the measurement bridges. If a value other than 5 V or 10 V is set, bridge measurement is
no longer possible!
5.8.8 Bandwidth
The channels' maximum sampling rate is 100 kHz(10 µs).
The analog bandwidth (without digital low-pass filtering) is 48 kHz (-3 dB).
