Preliminary Notes

Rear panel functions.
1.
The generator output impedance is
600n,
and may be directly connected to loads of
600n
or
higher impedances. When the impedances require matching, use a high grade matching
transformer; for square wave output, use a suitable resistance pad to insure "clean"
waveforms.
2.
A blocking capacitor should be connected in senes with the "hot" output lead when DC
voltage is present in the test circuit. This capacitor must have low reactance at the lowest test
frequency and proper voltage rating.
3.
Do not apply more than lOVrms at the OUTPUT and SYNC terminals.
4.
Use short connecting leads. Long unshielded leads will pick up extraneous noise; long shielded
leads will degrade the high frequency characteristics, especially at square wave output.
5.
Allow about one minute for circuit stabilization after the AC power has been turned on. (Sine
wave signals will show effects of clipping unless this precaution is taken. )
6.
Press only one FREQ_ RANGE switch at one time.
