EMCTEST
Transverse Electro Magnetic (TEM) cell or Crawford cell (named after its inventor) is used to generate accurate electromagnetic waves over a wide frequency range: DC (0 Hz) to GHz., EM waves generated in the cell propagate in transverse mode and have the same characteristics as a plane wave. It can be used to calibrate E-field broadband probes for testing radiated E-field immunity as well as for measuring radiated emission from a product with a spectrum analyzer/EMI receiver.TEM cell generates a consistent electromagnetic field for testing small RF devices such as wireless pagers, receivers, portable phones, etc.

EM-1 Econo™ -
Bio-Rad Laboratories
The Model EM-1 Econo UV monitor is a single-wavelength detector for flowthrough monitoring of effluents from chromatographic columns, centrifugation gradients, and other devices. The monitor consists of a control unit and an optics module that includes both 254 and 280 nm filters and a 2 mm pathlength flow cell. Connection is via Luer-Lok fittings for quick, easy changes.

EM Electronics
The EM A10 is a low level amplifier module for sensitive measurements, data collection and systems, where signals below 1 nanovolt may be measured. It is ideal for the input unit for precision voltage measuring systems, requiring voltage sensitivity for measuring low noise and low impedance sources. The noise level of the A10 is equivalent to a perfect resistor of about 20 ohms. When used with a digital voltmeter, steady one nanovolt digits may be displayed, with a response time constant of less than a second. The input voltage stability of the A10 is very high, with the drift around a nanovolt per degree C. The input connectors are made from pure copper. The input impedance is very high, and is time dependent, determined by the loop gain.

EM-6924 | 28 MHz – 1GHz -
Electro-Metrics Corp.
The EM-6924 tuned dipole set is the reference antenna for FCC and VDE measurements in the 28-1000 MHz range. Results from other linearly polarized antennas in the certifications process must be correlated with the results obtained from a tuned dipole.

EM-6879 | 10 KHz – 30 MHz -
Electro-Metrics Corp.
The EM-6879 Loop Antenna is used for magnetic field measurements over the frequency range of 10 kHz to 30 MHz. The EM-6879 is designed for use with any 50 ohm Receiver System. The antenna has a balanced Faraday shield that reduces its response to electric fields to a vanishingly small amount so that it can produce a practically pure magnetic field response.

EM-6869 | 9 KHz – 50 MHz -
Electro-Metrics Corp.
The Electro-Metrics EM-6869 Active Loop Antenna is used with any receiver or spectrum analyzer with 50 ohm input and covers the frequency range of 9 kHz to 50 MHz.
-
EM-6876 | 9 KHz – 30 MHz -
Electro-Metrics Corp.
The Electro-Metrics EM-6876 Active Loop Antenna is used with EMI Receivers and Spectrum Analyzers with 50 ohm input and covers the frequency range of 9 kHz to 30 MHz.

EM-6912A | 30 Mhz – 300 MHz -
Electro-Metrics Corp.
A balun, feedline, and element cage give the Electro-Metrics EM-6912A response curves that are almost linear, making it ideal for swept measurements. An added benefit is that the EM-6912A has an improved BALUN design, which makes it insensitive to changes of orientation while vertically polarized. Readings obtained will be the same no matter which element is closest to the ground plane, eliminating a potential source of measurement error.
