Model 39000 Hydrophone Signal Conditioner

Our Model 39000 Hydrophone Analog Signal Conditioning/Filter System provides up to 210 channels of fully programmable hydrophone signal conditioning. The 39000

15-slot rugged mainframe has a variety of high performance filter/amplifier plug-in cards to choose from with characteristics such as low-pass and band-pass functions, as well as, three traditional filter response types of Butterworth, Bessel and Elliptic. The 39000 System is ideal for conditioning low-level voltage signal inputs in front of high-resolution data acquisition systems.

Model FLX-3007 Filter/Amplifier Signal Conditioner

The NEW Krohn-Hite Model FLX-3007 Flexible Instrumentation Chassis provides a rugged, low cost, flexible platform for up to 7 high performance instruments sharing the same compact chassis. With the FLX-3007 Chassis, you get the functionality and features needed from a broad and growing selection of plug-in cards, avoiding the costs associated with larger systems that are not needed. The FLX-3007 platform can be assembled with up to 7 plug-in cards that you specify. It can be configured into a single channel signal conditioner or it can be expanded into a channel management system when needed; and since all FLX plug-in cards are all compatible, adding new cards is easy and economical. Side-by-side rack mounting is also available when high channel count is needed in a 5.25” X 19” rack spacing.

Low Noise Differential Preamplifier ↓

PERFORMANCE

The Model 7000 Low Noise Differential Preamplifier provides a high gain amplification to 1MHz with an AC output derived from a very low noise FET instrumentation amplifier and an optional DC (RMS-to-DC converted) output. The Model 7000 has fixed gain settings of x1 (0dB), x10 (20dB), x100 (40dB) and x1000 (60dB) over a selectable bandwidths of 100Hz, 1kHz (HP), 3kHz, 30kHz, 100kHz and 1MHz (LP Off). Noise referred to input is 7nV √ Hz and common mode rejection is >100dB at

1kHz. The Model 7000 provides momentary pushbutton switches that control coupling, bandwidth, gain and channel on/off selections. BNC connectors are provided for single-ended and differential input, ac output, and dc output (optional) connections.

APPLICATIONS

The Model 7000 is very useful for troubleshooting sources of noise, amplifiers, power supplies and various other electronic circuits. The Model 7000 is an excellent tool as a preamp for amplifying low level input signals to oscilloscopes or other devices.

PERFORMANCE

The Model 6620A provides precision phase measurements with a typical accuracy of 0.02° and a resolution of 0.01° over most of the frequency range. It will accept a wide range of input signal levels from 10mVrms to 320V rms and input waveforms including sine, triangle, square and pulses. A 5 digit LED display provides continuous direct readout of phase angles between 0.00° and 360.00° or ±180°. These two ranges can be manually or automatically selected.

APPLICATIONS

The 6620A is the ideal instrument for precision phase angle measurements and provides more performance/dollar than any other phasemeter in its class. A broad range of applications include monitoring servo control systems, low impedance measurements, adjustment of crystal resonance, testing and adjustment of filter networks, controlling laser trimming of resistor networks, measurements in ac power systems, secondary standard and general testing and measurement.
