CAT-5 Video Receivers
Analog Devices high speed, differential CAT-5 video receivers and equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. Our video receivers provide excellent common-mode rejection that enables the use of low cost, unshielded twisted pair cables in noisy environments.

Audio Generator
AG-51
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.

Sound Level Meters
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, asound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.

GPS/GNSS Anti-Jam Antenna
8230 AJ
The 8230AJ anti-jam antenna is a high gain (40 dB) GNSS outdoor antenna with a unique conical antenna pattern that rejects interference from the horizon. The antenna rejects signals at lower elevation angles – where most of the interference comes from – and only receives signals from higher elevation angles where the true satellites are. This way, you get all the performance and timing accuracy you would with a standard antenna plus 20 dB or more of interference rejection.It uses a three-stage low noise amplifier, a mid- section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The antenna covers GPS L1, GLONASS L1, BeiDou B1, Galileo E1, and QZSS L1.
