General Information
DYNAMIC RANGE:
Spurious Responses: (which includes image, out of band and harmonic
distortion ) referred to a single signal whose ampl itude is ::;; RAN G E setting and
whose frequency is
Termi nated ( 501 7 50) input
< - 8 0 d B
High Impedance ( 1 M O ) input
< - 8 0 dB; except second harmonic distortion, < - 7 0 d B
Intermodulation Distortio n : for two signals, each at least 6 d B below the
RAN G E setti ng and separated i n frequency by at least 1 00 Hz, referred to the
larger of the two signals.
Terminated ( 501 7 50) in put
