7.7 Performance Test
FRA5014 7-4
7.7.1 Frequency accuracy test
Connection:
OUTPUT OSCILLATOR → frequency counter input
Setting: After initializing settings, set frequency as 100 kHz, amplitude as 1 Vrms/open, and
output on.
Measurement: Use a frequency counter to measure the frequency.
Judgment: Normal if ±50 ppm (99.9950 kHz to 100.0050 kHz).
7.7.2 Oscillator AC amplitude accuracy test
Connection: OUTPUT OSCILLATOR
→
AC voltmeter input
Setting: After initializing settings, set the frequency and the AC amplitude (Vrms/open) as
follows.
Turn output on to have the settings reflected in the output.
Measurement: Use an AC voltmeter to measure the output voltage.
Judgment: Normal if within the ranges specified in the following table.

7.7.3 Oscillator DC bias accuracy test
Connection: OUTPUT OSCILLATOR
→
DC voltmeter input
Setting: After initializing settings, set AC amplitude as 0 Vrms and DC bias (V/open) as
shown in the following table.
Turn output on to have the settings reflected in the output.
Measurement: Use a DC voltmeter to measure the voltage.
Judgment: Normal if within the ranges specified in the following table.
