Adopting the condition of equal inductors for the pre-amplifier
I then took the pre-amplifier
, electrode apparatus and my laptop out into the field to see if I could find and record this signal in other locations.
For this scheme, the needed probe hardware is minimal, there are no critical alignment issues, and the same pre-amplifier
that is normally used for sensing the tunneling current when using the scanning tunneling microscope probe can be used to amplify the tuning-fork signal.
Available in two configurations, the HL 6000 system includes: a base controller, pre-amplifier
, two piezo ceramic accelerometers, head phones, 120 VAC battery charger, all necessary cables and manual.
The unit can be used as a booster, inline or pre-amplifier
, and has an RS-232 serial interface for system integration and diagnostics.
The company's RC-995 BX stereo pre-amplifier
was designed in response to "numerous" consumer requests for a pre-amplifier
with a high-performance phonograph stage, said Michael Bartlett, Rotel's vice president and general manager.
The IDT GX72170 is a broadband, low power consumption, single channel amplifier die, which integrates a linear pre-amplifier
and a post-amplifier with AC-coupled 100?
Naim NAC 552 reference analog pre-amplifier
with reference power supply
Finally, an erbium-doped fiber pre-amplifier
boosts the return optical signal.
Editor's Note: The K-Factor Scaler is used as a pre-amplifier
to amplify the pulse output from turbine flow meters such as the Ultima F6202-F (SAE) and the F6222-F (BSPP) for transmission to F6600 (AC) and F6650 (DC) Series digital displays.
Audio capability of the kit is supported by the inclusion of audio record and playback circuitry in the processor, coupled with an on-board audio pre-amplifier
, integrated in the image sensor.
