Analog output data
Important: ECG signal output to synchronize ultrasound units (not for diagnostic
purposes!)
- lead II standard (configurable with CardioSoft/CardioSys V 3.0 and later)
- ECG lead selectable (from CORINA & CardioSoft Version V3.0)
- floating output (± 1500 V referred to ground / chassis)
- 1-V output signal per 1-mV input signal, U
max
= ± 10 V
- offset accuracy over the entire range < 300 mV (typically, full deflection)
- accuracy over the entire range (typically) < 3%
- R
L
min 2kOhm
- delay < 10 ms
- pacing pulse filtered out
- unedited signal, unfiltered, no ADS
- short-circuit-proof
Power supply
From plug-in power supply unit type FW 7324/2 supplied with the system
The newer PCB version, used in CORINA 101 118 31...36 and 101 118 41...44 you can
choose between the FW 7324/2 power supply or the new SW 172 widerange power
supply. The default is the FW 7324/2 power supply.
