MEASUREMENT METHOD (CONT.)
7. Bias Voltage (V
)
The DC voltage at Pin 6 is measured with no input signal.
8. Voltage Gain (GVA)
The voltage gain equation is as follows:
GVA = 20 log
V2/V1
Where V1 is the input voltage at TP1 and V2 is the measured voltage at TP5 (TP7). Furthermore, V1 is the input voltage
at TP2 and V2 is the measured voltage at TP3 (TP5).
9. Differential Gain (DG)
The differential gain is measured at TP5 (TP7) when a staircase waveform of 10 steps is applied to TP1.
10. Differential Phase (DP)
The differential phase is measured at TP5 (TP7) when a staircase waveform of 10 steps is applied to TP1.
11. Frequency Response (fr)
The frequency response equation is as follows:
fr = 20 log
V2/V1
Where V1 is the measured TP7 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP7 voltage
when the TP1 input frequency is set to 5 MHz. Furthermore, V1 is the measured TP3 (TP5) voltage when the TP2 input
frequency is set to 1 MHz and V2 is the measured TP3 (TP5) voltage when the TP2 input frequency is set to 5 MHz.
12. Cross Talk 1 (CT1)
The cross talk equation is as follows:
CT1 = 20 log
V1/V2
Where V1 is measured at TP3 when a 1 MHz 1 V
P-P
input signal is applied to TP1 and V2 is measured at TP3 when a 1
MHz 1 V
P-P
input signal is applied to TP2.
13. Cross Talk 2 (CT2)
The cross talk equation is as follows:
CT2 = 20 log
V1/V2
Where V1 is measured at TP7 when a 1 MHz 1 V
P-P
input signal is applied to TP2 and V2 is measured at TP7 when a 1
MHz 1 V
P-P
input signal is applied to TP1.
