Mains Connection

 

Mains voltage:             230 VAC/115 V AC, 50 … 60 Hz, 20 VA

Mains switch:               ON/OFF with pilot lamp

Mains fuse:                   F1 = 0.1 A slow (at 230 V), primary side

                                       F1 = 0.2 A slow (at 115V), secondary side

 

Power is supplied through a 3-pin appliance connector on the rear side of the unit.

 

Change-over from 230 V to 115 V (110 V) mains voltage is done by resoldering jumpers (0 W resistors) inside the unit (see fig.1).

 

Warning: Before dismantling the unit pull the mains plug!

 

 

Oscillator Current Supply

 

The oscillator current supply alternatively supplies a continuous signal or meander-from signal clocked with 1 kHz, the voltage of which is continuously adjustable by means of a potentiometer. Selection is done by plugging in a 4 mm connecting plug. The current consumption can be measured as a voltage value via a 1 W resistor and afterwards be calculated.

 

Voltage range:              -4 V … -9 V

Max. Current:                 500 mA

 

Fastening Screws

 

The unit can be screwed out of the case by loosening the six fastening screws.

Warning: Before dismantling the unit pull the main plug!

 

Modulator Signal

 

Amplitude of the modulator signal continuously adjustable by means of potentiometer. The signal is a meander-form voltage clocked with 1 kHz and used for the PIN Modulator (Type 4521).

 

Voltage range:              -1 … -6 V

Max. current:                  50 mA

 

Constant Voltage Source

 

High-ohmic voltage source. It supplies a constant bias voltage for the Schottky diode of the VSWR Detector (Type 4556).

 

Voltage:            -9 V

 

Mounting Rail

 

Mounting rail for setting up experiments with the components

 

Length: 60 cm

 

Scale

 

Millimetre scale for accurate positioning of the components on the mounting rail.
