calibration-voltage generator.
s generator provides a square-wave voltage of 1 V
Yo at a frequency of about 2.5 kHz.
ticule-illumination circuit, which provides a
icule illumination which is independent of mains-
age variations.
tage stabilizer, which keeps the 23 V input voltage
he converter at a constant value during mains-
age and load variations.
stabilizer provides together with unit 10 (mains-
age transformer + rectifier) and the series
ator on the rear of the instrument, the supply
age for the converter.
nector unit 6. This unit consists of a square-wave
verter with a frequency of about 18 kHz.
power pack provides all supply voltages for the
rument, viz. + and —23 V, + and —95 V, —1600 V
+8500 V.
