Review Xetron Elog 10 USB

The instrument acts, is aesthetically pleasing and takes up little space, but...

• ... it is difficult to use and has the following problems:
• the software is complicated to install 
• and moreover I stopped because it requires me to disable the computer's security system. Unacceptable
• the batteries have a very limited life span

Returned item.

Bruel & Kjaer 2693 Nexus

Specially suited for automotive use.
Developed in association with major car manufacturers.

For use with:

• charge accelerometers
• hydrophones
• force trasducers
• condenser microphone
• CCLD accelerometers
• CCLD preamplifiers
• voltage input
• sound intensity probes

Field recording of vibration and acoustic signals

Specially suitable for applications where shocks and impulses occur such as gas turbine testing and munitions testing (Types 2692-C and -D only)

NEXUS can be reconfigured if your requirements change.

If, for example, you have a 1-ch. Charge Conditioning Amplifier, it can be updated to a 2-ch. Charge/2-ch. Microphone Conditioning Amplifier.

Hardware/software updates, for example, auxiliary modules with A-, B-, C- and D-weighting filters or integration, make the concept even more flexible.

HP 16453A Specification

https://testequipment.center/Product_Documents/Agilent-16453A-Specifications-308E1.pdf

HP 16453A DIELECTRIC MATERIAL TEST FIXTURE

 The 16453A has been designed to operate specifically with the 4291A RF Impedance/Material Analyzer equipped with the Option 002 (which provides the permittivity measurement function for dielectric material).

 The 16453A is designed for accurate dielectric constant and loss tangent measurements on the E4991A/4291A/B.

It employs the parallel plate method, which sandwiches the material between two electrodes to form a capacitor.

The E4991A/4291A/B measures the capacitance created from the fixure, and option 002 firmware calculates the relative complex permittivity as described in the 16451B. Adjustment to insure parallel electrodes is required when using the 16451B. This adjustment is not required with the 16453A because the fixure has a flexible electrode that adjusts automatically to the material surface.

Frequency:
1 MHz to 1 GHz

Sample size (smooth sheets only):
thickness: 0.3 mm to 3 mm
diameter: ≥ 15 mm

The Type 5612 Spectrum Shaper is used to modify the overall frequency response of acoustic and electroacoustic systems.

Its 36 individually regulated , narrow -pass bands with good roll-off attenuation also make it suited for use as a high-pass, low-pass, or a bandpass filter which can be adjusted for many applications.

• Thirty-six 1 / 3 octave band-pass filters each with its own attenuator
• Frequency range from 11 Hz to 45 kHz
• Filters conform to IEC 225-1966, ANSI S1.11- 1966 Class III and DIN 45 652
• Single filter notching of approximately 50 dB
• Roll-off attenuation better than 40 dB per octave
• Individual test point on each channel to aid adjustment
• Attenuator slider knobs to give a visual representation of the selected spectrum shape
