Test Conditions
1. Measure the power-supply current when no input signal is supplied.
2. Measure the pin voltages on each pin when no input signal is supplied.
3. Let VOUT be the OUT pin signal amplitude when a 200-kHz 350-mVp-p sine wave is input.
Then, the voltage gain (GV) for each of the R-Y and B-Y I/O systems is given by:
VOUT [mVp-p]
GV = 20log ——————— [dB]
350 [mVp-p]
The R-Y and B-Y voltage gains (
G
V) are:
G
V = | GV (R-Y) –GV (B-Y)|
4. Let V1 be the OUT pin output when a 100-kHz 200-mVp-p sine wave is input.
Let V2 be the OUT pin output when a 1-MHz 200-mVp-p sine wave is input.
V2 [mVp-p]
Gf = 20log ——————— [dB]
V1 [mVp-p]
5. Input a 5-stage step waveform (350 mVp-p) and measure the levels a and b in the output signals.
Perform those measurements for both positive phase and inverted signal inputs.
<Positive phase signal input>
<Inverted signal input>
6. Measure the noise spectrum of the output signal when no input is supplied and read the 4-MHz peak.
7. Pass the output signal through a 2-MHz low-pass filter and a 100-kHz high-pass filter. Then, measure that output with
a noise meter, when no input signal is supplied. Use a 2-MHz low-pass filter with an attenuation of –60 dB at 4-MHz.
8. Input a 200-kHz 350-mVp-p sine wave.
Let V1 be the OUT pin output when SW2 is set to a.
Let V2 be the OUT pin output when SW2 is set to b.
V1 [mVp-p] – V2 [mVp-p]
ZO = ———————————— × 500 []
V2 [mVp-p]
9. Measure the delay time of the OUT pin output with respect to the input signal. When taking this measurement, exclude
the delay associated with the low-pass filter.
