Electronic control unit consisting of a quartz-controlled transmitter (40 kHz)
with two outputs and one input with amplifier and rectifier.

Modes:
- CONTINUE: output signal is continuously transmitted
(for diffraction, superposition and absorption experiments)
- IMPULSE: Output signal is transmitted as a pulsation
(for distance measurements, sonar principle, etc., in conjunction with an oscilloscope)
- SHOT: Non-recurring pulsation transmission when button is pushed
(for time and distance measurements, in conjunction with an oscilloscope)
The outputs and inputs have two-colour LEDs to indicate the transmit or receive signal, but also signal the battery status or a possible overload status of the receiver

Analogue output via two 4 mm safety sockets
Data output for oscilloscope, counter or computer

Power supply: Battery operation (9 V battery included)
or external supply via e.g. Mains transformer 12V DC/2A P3130-1P
Dimensions: approx. 160 x 120 x 42 mm
Mass: approx. 325 g

additionally required:
P1860-1S Ultrasonic transmitter
P1860-1E Ultrasonic receiver
