Capabilities Description
Input characteristics
Channel Separation (High Resolution Mode)
This is a measurement of the level of the driven channel
with respect to the undriven channel with a bandpass
filter centered on the driven channel frequency. The
measurement is primarily noise-limited, therefore,
measured values improve as input amplitude increases.
Channels A and B Equal Gain Settings
(both channel input ranges at +8 dBu)
Typically ≥110 dB, 20 Hz to 5 kHz, from +2 dBu on the +2 dBu input range
through +30 dBu on the +32 dBu input range.
10 Hz to 5 kHz ≥100 dB
>5 kHz to 20 kHz ≥90 dB
Undriven Channel Set to Auto Range
15 Hz to 5 kHz ≥120 dB (noise-limited)
>5 kHz to 20 kHz ≥110 dB
Channel Separation (High Bandwidth Mode)
Channels A and B Equal Input range Settings
(driven input = +8 dBu on +8 dBu input range)
CH A into CH B
70 Hz to 5 kHz ≥85 dB
>5 kHz to 40 kHz ≥75 dB
>40 kHz to 80 kHz ≥65 dB
CH B into CH A
70 Hz to 5 kHz ≥85 dB
>5 kHz to 40 kHz ≥80 dB
>40 kHz to 80 kHz ≥70 dB (typically ≥85 dB)
Undriven Channel Set to Autorange
(driven input = +8 dBu on +8 dBu input range)
CH A into CH B
70 Hz to 5 kHz ≥115 dB
>5 kHz to 40 kHz ≥105 dB
>40 kHz to 80 kHz ≥ 95 dB
CH B into CH A
70 Hz to 5 kHz ≥112 dB
>5 kHz to 40 kHz ≥110 dB
>40 kHz to 80 kHz ≥108 dB
