external device. Calibration.
The analysis of a

The Voltage -
Frequency Caracteriograph.
The coordinate oscilloscope
mode (dynamic characteriograph) is
activated by the button Y2 (Y1)
On/Off or key X.
Real devices with an additional input are
used for comparison of frequencies and phases of signals. You can
do simple experiences with phase-shifting C or L, as shown in
figure, or to connect with generator, having established
different frequencies on channels (about the generator you can see here).

It’s interested to capture the
characteristics of the nonlinear components - various diodes,
termoresistors etc. Set the switch S1 (see circuit of the external device fig. 1) in the position Osc, connect the
switch S2. Activate the1 channel of the generator,
establish the maximal sine wave voltage to avoid distortions -
flat tops (see by scope).
There are options of the representation of four kinds of the
dependence for the characteriograph. The coordinate axes are
marked and numbered in true voltage or current, if the
calibration is made and also the size of resistance R4 is
precisely established.
