NC input, pulse cycle = 1kHz,
44pin = 2V applied, pulse width = 1μs,
at 200mVp-o pulse input (after MPX-VCO
adjustment), measurement at pin 24.
NC input (pin 59), 44pin = 2V applied,
measure the pulse input level at which the
noise canceller starts operation,
pulse cycle = 1kHz, pulse width = 1μs
S-meter (AC) input (pin 57), 44pin = 0V
applied, measure the pulse input level at
which the noise canceller starts operation,
pulse cycle = 1kHz, pulse width = 1μs
S-meter (AC) input (pin 57),
pulse cycle = 1kHz, pulse width = 1μs,
measurement at pin 24. 44pin = 1.5V
S-meter (AC) input (pin 57), measure the
pulse input level at which the noise canceller
