HI-913 -
Metrix
This Hardy Shaker provides the ability to set the amplitude and change the frequency range without the amplitude changing. This automation makes conducting a test easier. A test can be conducted on a vibration transducer and manually recorded. Multiple tests are not saved; for multiple tests use the HI-903 or HI-803 units. The HI-913 is used for testing from 7 to 10,000 Hz, it offers adjustable frequency and vibration levels. This provides a reference source for verifying the accuracy of vibration transducers, connectors, cabling and instruments or instrumentation systems. The HI-913 has a ruggedized suspension system that can support heavy transducers (up to 800 grams - see frequency limits in the manual). The HI-913 has a built-in battery charger that can operate on 120 or 240 VAC. The unit comes in a rugged Pelican case.

B-1020-C -
ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.
