Main Signal Output Connectors
The Main Signal is available at one of two BNC connectors located on the
I—, front and rear panels. The front-panel [Rear Only] key selects which of
S rn connectors has the main signal output. The active connector is
indicated by the rear-only indicator; an illuminated rear-only indicator
4^ denotes that the rear-panel output is active.
Both outputs share the same ground and may be floated up to ±42 volts
peak relative to earth ground.
Caution The maximum peak voltage (ac + dc) that can be safely applied between chassis and
the outer conductor of the HP 3225B input and output connectors is ±42 volts peak.
Note When the high voltage option (option 002) is installed, the key by the Main Signal
output connector (labeled “40 Vpp, 40 mA, 0-1 MHz”) controls the high voltage
amplifier. On these instruments, the rear-panel Main Signal output connector
is inactive.
The specifications for the Main Signal output impedance and return loss are:
Impedance: 500 ± 10 from 0 to 10 kHz
Return Loss; 20 dB 10 kHz to 20 MHz except
> 10 dB for > 3V, 5 MHz to 20 MHz
High Voltage < 20 at dc
(option 002); < 100 at 1 MHz
