25 Hz-20 kHz
≤(0.0025% + 3.0 µV), 80 kHz BW [-92 dB]
10 Hz-50 kHz
≤(0.010% + 10 µV), >300 kHz BW [-80 dB]
Minimum Input
25 mV for specified accuracy in AUTO TUNE
mode, 800 µV [-60 dBu] in other modes.
Nulling Time
Typically 2-3 seconds above 25 Hz, Increases in
a “1/V” fashion for inputs below 25 mV [-30 dBu]
Note 6 System specification including contribution from generator. Generator residual THD
may limit system performance below 25 Hz if output is >20.0 Vrms balanced, or
10.0 Vrms unbalanced.
