2
20 Hz–50 kHz only. Decrease maximum output by a factor of 2 (–6.02 dB) for the full 10 Hz–204 kHz range.
3
System specification measured with the 2700 series analog analyzer set to the indicated measurement
bandwidth (BW). Generator amplitude setting must be £12 Vrms balanced or £6 Vrms unbalanced for
specified performance below 30 Hz. At higher amplitude settings generator THD derates to 0.0020% from
20 Hz–30 Hz.
4
Individual harmonics are typically <–130 dBc at 1 kHz, and <–120 dBc from 25 Hz to 20 kHz measured with a
passive notch filter and FFT analyzer.
5
Calibration with other amplitude units is based upon an equivalent sinewave having the same Vpp amplitude.
6
System specification measured with the 2700 series analog analyzer at any amplitude ³200 mVrms.
