HP 3325B User Manual

Selecting the Output Function
The Main Function Keys and Indicators
Pressing one of the five Main Function keys selects the function output of
the HP 3325B. The indicator adjacent to a function key illuminates when
that function is selected. Pressing the function key for the selected function
a second time removes the ac component of the signal leaving only the
selected dc offset (if any is entered). Removing the ac signal in this way,
automatically displays dc offset and illuminates the de offset entry indicator.
Pressing the disabled function key again restores the ac signal. Unless a dc
offset is entered, the output signi for each function is centered about zero
volts.
The DC Offset indicator illuminates when a non-zero dc offset exists.
The standard instrument signal output must be terminated by an external 50Q
load or sine wave distortion and square wave overshoot may result, particularly at
the higher frequencies (> 1 MHz). All specifications apply with a 500 load
connected to the HP 3325B main signal output except where indicated (table 3-1
Specifications).
