1.2.4.2 Deviation factor ks
slow speed: ks =0 fast speed: ks =10
1.2.4.3 Level factor kv
When V=1V, kv =0;
When V = 0.3V, kv = 1;
When V = 0.1V, kv = 4.
1.2.4.4 Frequency factor kf
When f = 100 Hz, 120 Hz or 1 kHz, kf = 0;
When f = 10 kHz, kf = 0.5.
1.2.5 Test signal frequency
Test signal: sine wave
Four frequencies are available: 100Hz, 120 Hz, 1 kHz, 10 kHz
Accuracy: 0.02%.
1.2.6 Test signal level
Three levels are available: 0.1V, 0.3V, 1.0V (effective value)
Accuracy: ±10% (The set value of the measurement level is the value set when
test terminals are opened HD and HS should be connected)
Due to the output impedance of the signal source, the actual level applied upon
the component under test may be different from the set value.
1.2.7 Output impedance of measurement signal
Output impedance: 30 Ω (default value) and 100 Ω , without requirement of
accuracy.
