E-836.1G Piezo Amplifier
INFORMATION
The output piezo voltage contains the switching frequency of the internal DC/DC
transducer of the E-836.1G (600 kHz). This frequency has no effect on the motion of
the stage, however. For this reason, the measurement of the piezo voltage (e.g. with
a digital oscilloscope) is
not
suitable for determining the motion resolution of the
stage.
Measure the motion of the stage directly, e.g. with optical methods or high-
resolution sensors.
INFORMATION
When it is switched off, the E-836.1G generates a voltage spike at the output for the
piezo voltage. A connected stage will execute a corresponding motion, which can be
noticeable as a clicking sound. This behavior is unproblematic and does
not
affect
the stage.
6.2 Switching on the E-836.1G
Prerequisite
You have read and understood the general notes on start-up (p. 17).
You have connected the power supply to the E-836.1G (p. 14).
When a signal source is connected to the
Control In
BNC socket: The signal
source is switched off or its output is 0 V.
The
DC Offset
potentiometer is turned fully counterclockwise.
Switching on the E-836.1G
Connect the power cord of the power supply with the power socket.
The
Power
LED on the front panel shows the ready state of the E-836.1G:
−
Green: E-836.1G is ready for operation
−
Off: E-836.1G is not ready for operation
