Equipment Setup
Power
The AC Power supply plugs into the Power Input of the String Vibrator. It drives the String
Vibrator with a constant-frequency, constant-amplitude sine wave. The driving frequency equals
the frequency of the mains power supply (50 or 60 Hz in most countries).
If you would like to drive the String Vibrator with a variable signal, you can use any function
generator capable of producing a 10 V amplitude sine wave at up to 1 A, including the following:
• Sine Wave Generator (WA-9867)
• Digital Function Generator (PI-9587)
• 750 or 700 Interface with Power Amplifier II (CI-6552A)
Mounting Options
The String Vibrator can be fastened to a table in a variety of ways.
C-Clamp
Two recessed Clamping Surfaces on the
String Vibrator allow it to be secured to a
table with a C-clamp. You must use a C-
clamp wide enough to accommodate the
thickness of the tabletop plus 3 cm (1¼
inch).
The PASCO Small C-Clamp (SE-7286,
6-pack) can clamp the String Vibrator to
tables up to 5 cm (2¾ inches) thick; the
Large C-Clamp (SE-7285, 6-pack)
accommodates tables up to 7 cm (2¾
inches) thick.
