(Figure 58).
– 5 kHz (D1) – Left half of screen
1: Vc - Voltage of 5 kHz oscillator.
2: Vc-Vn - Voltage of 5 kHz oscillator minus null voltage.
3: Vsc - Voltage of 5 kHz oscillator with on-board test
network engaged.
4: Vsc - Vn - Voltage of 5 kHz oscillator with the on-board test
network engaged minus null voltage.
– 2 MHz (D2) – Right half of screen
5: Vc - Voltage of 2 MHz oscillator.
6: Vc - Vn - Voltage of 2 MHz oscillator minus null voltage.
7: Vsc - Voltage of 2 MHz oscillator with on-board test
network engaged.
8: Vsc - Vn - Voltage of 2 MHz oscillator with on-board test
