This document is a supplement to the HP 89044 Multifunction
Synthesizer Basic Operation and Application
guide and the Operation and
Calibration Manual.
It contains operation and reference information
specific to
HP 8904As with Option 006 installed.
The HP 8904A Option 006 replaces the standard 50R output of
Output
1 with a true transformer-coupled 600R output. This 600R
full-floating output provides higher power than the standard 50R
output, and can be configured as either single-ended or balanced.
This capability is only available for Output 1.
Option 006 can not be installed in combination with Option 004 -
Rear Panel Outputs. A second output can be installed to provide a
50Sl output by ordering Option 002.
The amplitude displayed on the instrument’s front panel assumes an
external load
of 600R. Connecting a high impedance load results in
an amplitude of up to twice that indicated for Output 1.
The Option 006 output is specified for sinewaves only, and for the
frequency range of
30 Hz to 100 kHz. Output frequencies up to
200 kHz are available if the typical -4dB rolloff characteristic of the
transformer is acceptable.
Due to the nature of a transformer coupled output, the Option 006
output can not pass DC or low frequency signals. This characteristic
prevents Option
006 from outputting digital sequences provided with
Option
001.
Refer to the accompanying specifications for additional operating
parameters.
