∗ CTL switching level is substituted by performing the above measurements.

∗1 Connect a distortion meter to the output. After adding a f = 1kHz sine wave input from the OSC, adjust the input level so that the output

distortion is 1.0%. The output voltage at that time is the maximum output level Vom [VP-P].

∗2 Apply to the input pin a VIN = 1.0VP-P, f = 1MHz sine wave input.

Voltage gain GV = 20-log (VOUT / VIN)

∗3 Apply to the input pin VIN = 1.0VP-P, f = 1MHz and 10MHz sine wave inputs.

Frequency characteristics Gf = GV (f = 1MHz) – GV (f = 10MHz)

∗4 Apply to the input pin a VIN = 1.0VP-P, f = 4.43MHz sine wave input.

Interchannel crosstalk Cta = 20log (VOUT / VIN)
