3.2.8 INPUTS AND OUTPUTS
The oscilloscope is equipped with several inputs and outputs to provide special
functions and applications.
All standard and optionai sockets are described below:
3.2.8.1 Standard
SOCKET DESCRIPTION
A BNC input socket for channel A. Probe range indicator
identifies attenuation of probe connected and this is
compensated for in the LCD display for vertical deflection.
(only active with probes that are provided with range indicator).
B BNC input socket for channel B. Probe range indicator
identifies attenuation of probe connected and this is
compensated for in the LCD display for vertical deflection.
(only active with probes that are provided with range indicator).
EXT BNC input socket;
When EXT input is selected via the time-base the signal
input is used for external triggering.
When EXT input socket is selected via X DEFL, the
horizontal deflection is determined by the signal applied
to this socket.
CAL Output socket providing a 1,2 V{p-p), 2 kHz approx.
square-wave voltage. To be used for probe compensation
or to calibrate the vertical deflection AMPL. control.
LINE IN Input socket for mains supply: 100 V...240 V(ac),
45 Hz.. .440 Hz.
ANALOG PLOT Output socket providing the plot signals Y PLOT, X PLOT
OUT and PENLIFT. Penlift can be defined in "APPL" application
preselect (see chapter 7).
Sensitivity PLOT X and PLOT Y: 100 mV/div
Penlift; open collector
