OSC CH1 CH2
FRA5087
OSC CH1 CH2
CH1 dynamic range measurement CH2 dynamic range measurement
c) Procedure
Set the analyzer mode as follows and sweep with the FRA5087.
Read the minimum dBR measuring results from the LCD screen.
Analyzer mode for measuring CH1 dynamic range: CH2/CH1
Analyzer mode for measuring CH2 dynamic range: CH1/CH2
d) Judgment
Connection Minimum measured value Tolerance
CH1 (10 Hz to 1 MHz) dBR= dB 140 dB typ
CH2 (10 Hz to 1 MHz) dBR= dB 140 dB typ
CH1 (1 MHz to 10 MHz) dBR= dB 80 dB typ
CH2 (1 MHz to 10 MHz) dBR= dB 80 dB typ
