Output Source Impedance Parameter (50 Ω into)
An impedance of 50
Ω
or 1 k
Ω
is selectable. There is no selection for the
Agilent 81110A when fitted with Agilent 81112A 3.8 V 330 MHz output
channels.

Load Impedance Parameter (50.0Ω)
Adjust the load impedance value expected at the output to compensate
for non-50
Ω
loads. The displayed level-parameters are then calculated
using this value and therefore represent the levels at a non-50
Ω
static
load.
Output Voltage and Power Protection

OTE
TETE
TE When an output is switched on, the instrument monitors the actual
voltage and current levels at the output. The output is automatically
switched off if voltage levels or power dissipation reach levels that could
damage the output circuits.
The available output levels for an output could therefore be limited by
external voltages, loads and the level settings of the other output if you
are using a dual channel instrument with outputs added at output 1 (see
Specifications).

TE On the screen of the Agilent 81110A with Agilent 81112A 3.8 V/330 MHz
outputs installed the second output status is displayed for differential
outputs. The instrument also assumes 50
Ω
load impedance and there is
no added outputs option available.
