Agilent Technologies E1446A Car Amplifier User Manual


 
Protection: Relay Trip. This disconnects the main output after
either a voltage or a current overload of non-transient duration. The
relay’s state can be queried and reset by software control.
Differential Outputs These are two outputs nominally out-of-phase.
Connectors: The + (in-phase) and - (antiphase) outputs have
separate ground-referenced BNC connectors.
Impedance: 50 or 75
, each side to ground
Drive Capability :
± 1V into 50 or 75

Characteristics
Maximum voltage gain from either input (with all attenuators set to
0 dB; accuracies shown are for DC):

Differential + + 1
± 1.0 % + 2± 1.0 %
Differential - -1
± 1.0 % -2 ± 1.0 %
Input channel attenuators: Each input channel has an independent
attenuator adjustable from 0 to 31 dB in steps of 1 dB.
Main output attenuator: Two settings, 0 or 20 dB attenuation.
(20 dB setting is not applicable when Rout = Low-Z.)
Attenuator DC accuracy: 0.1 dB for each attenuator
Offset Main Output Offset is adjustable with a DAC:
Nominal Range : + to - maximum output voltage (i.e.
± 10V or ± 20V)
Resolution : 16 bits
Accuracy:
± 0.5% of full-scale plus ± 0.7% of setting
Differential Outputs : Offset accuracy is
± 1% of maximum output
