MEASUREMENT METHOD
8. Total Harmonic Distortion (THD)
The TP2 signal is measured when a 1 kHz 1 V
input signal is applied to TP1.
THD is measured for the other channels in the same manner.
9. Maximum Output Voltage (V
)
A 1 kHz input signal is applied to TP1 and the amplitude is slowly increased. The output voltage at TP2 is measured at
the point the THD reaches 10%.
V
OUT(MAX)
is measured for the other channels in the same manner.
10. Cross Talk (CT)
The cross talk equation is as follows:
CT = 20 log
V1/V2
Where V1 is measured at output 3 when a 1 MHz 1 V
input signal is applied to input 1 or input 2. V2 is measured at output
3 when a 1 MHz 1 V
input signal is applied to input 3. Furthermore, V1 is measured at output 2 when a 1 MHz 1 V
input signal is applied to input 1 or input 3. V2 is measured at output 2 when a 1 MHz 1 V
input signal is applied to input
2. V1 is measured at output 1 when a 1 MHz 1 V
input signal is applied to input 2 or input 3. V2 is measured at output
1 when a MHz 1 V
P-P
input signal is applied to input 1.
11. Signal to Noise Ratio (S/N)
The signal to noise ratio is measured at TP3 when a pedestal input signal is applied to TP1.
12. Differential Gain (DG)
SW1 is closed to change the input bias voltage.
The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.
13. Differential Phase (DP)
SW1 is closed to change the input bias voltage.
The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.
