Page 4: General Information And Overview
Purpose and Description of the Device Purpose of the RF drives HF-D 200, HF-D 425 and HF-D 600 is the supply of AC voltages to Paul Ion Traps and other Quadrupole-type electrode setups for ion storage and manipulation. Unlike standard RF (radio- frequency) power amplifiers, the device is capable to handle capacitive loads, which are related to vacuum setups for ion trapping and storage. -

48pF/m, half the value of standard RG58 BNC cable. The smaller parasitic capacitance allows a higher degree of freedom since cable capacitance significantly contributes to the overall (terminal) capacitance, which must not exceed 100pF (each output) to meet the device specifications. www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884... -

When the manual switch lever is centered, a logic “LOW” level (0 Volts) disables, a logic level “HIGH” (+5 Volts) enables the RF outputs. The reaction time upon a change of this level is about 1 to 2 signal periods (see also section 4.3.1) www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884... - Page 7 A or B. This indicator may serve as coarse, but nevertheless important, check for correctly attached cables and circuitry on the outputs. However, a thorough cabling check is recommended before applying any signals to the outputs (see below, section 4.2). www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884...

The Offset Input allows for adding an additional (externally provided) offset to both output lines. This offset is linearly added (superposed) and may reside in the range between -300V and +300V. Note, that www.stahl-electronics.com phone: +49 6242-504882, fax: +49 6242 504884... -
