Measurement Setup and Putting into Operation
i
IMPORTANT!
Video output for test only.
It must be activated by
software for use.
Connect a monitor
using a coaxial cable
with BNC-type plug.
The mode input reacts like the identically named button and switches cyclically
between the various user modes.

Analog Outputs
Both analog outputs (x and z) have the same internal circuit.
Attributes
:
Output impedance:
50 Ohm
Output current:
max. 5 mA, no short circuit protection.
Fig. 6.11: Output circuit of the analog outputs
Recommendations
:
• Select the load resistor RL as high as possible for maximal accuracy. A resistance
of R
L
= 50 kOhm results in a scaling error of 0.1 %.
• The load capacitor C
L
can typically be 4.7 nF (ceramic capacitor) for noise
reduction. Pay attention on the cable capacity regarding the high frequency
limit (detail accuracy).
• Connect external devices with two shielded coaxial cables, whose shields provide
signal ground and must therefore not be connected to the plug case or the power
ground (0 VDC).

Video Output
Output impedance: 75 Ohm
Terminating resistor:
75 Ohm

For connection to a
higher level controller
shielded two-wire ca-
bles must be used, as
for the synchroni-
zation.
The cable shield here
must be connected to
the plug case.
