Level/Pulse Performance Characteristics
Level parameters: voltage or current, high
or low level, offset or amplitude.
On/off: relays connect/ disconnect output
(HiZ).
Load compensation: the actual load value
can be entered (forloads ≠ 50 Ω) to display
actual output values. (Applies to the
Agilent 81105A and Agilent 81111A only). Normal/complement: selectable.
Limit: programmable high and low levels
can be limited to protect the device-under-
test.
Channel Addition (with Agilent 81105A or Agilent 81111A output channels)
If the instrument is equipped with 2 output modules, channel 2 can be added to channel 1 internally. In this case the second output is
disabled. The additional fixed delay on the second channel is typ. 2.5 ns. The following parameters differ from the above specifications if
two output modules (Agilent 81105A/Agilent 81111A) are added.
Data Sheet 81100 Family of Pulse Pattern Generators 6
Level specifications are valid after a 5 ns (Agilent 81112A) or 30 ns (Agilent 81111A/Agilent 81105A) typical settling time.
