Preamplifiers
LNA Series
-
Low noise amplifier with 12.5 dB of gain covering the nominal frequency range 1 MHz to 3 GHz and can be used in the range from 200 kHz to 4 GHz. With its high gain and low noise figure, it will significantly increase the sensitivity of virtually all spectrum analyzers and other RF measuring instruments. All measuring instruments have a 'noise figure', which is a measure of how good the instrument is at measuring low level signals, the lower this figure, the better, although the lowest signal level will still be governed by the measurement bandwidth. A typical spectrum analyzer may have a noise figure of 20 dB or more, whereas a typical receiver may have a noise figure of 10 dB. The preamplifier has a noise figure of typically 4 dB, significantly enhancing the low level performance of such instruments, enabling signals that were previously masked by noise to be seen.

Voltage Detectors
JSC
-
The JSC family of devices provides a highly reliable way to determine if voltage is present downstream of the disconnector or circuit breaker knives during zero-energy shutdowns. They dramatically increase the safety of personnel performing maintenance on electrical equipment. When voltage is present downstream of the disconnector knives, one or more LEDs on the JSC-88A will remain illuminated. The JSC's compact design allows for direct installation on the disconnector door, starter, or control panel.

Test Voltage Indicators
PRV240FS
-
Verify your test tool works without unnecessary exposure to shock and arc flash. Make the process easy by using the PRV240FS Proving unit. Verifying that your T6 electrical tester is working properly reduces the need for personal protective equipment (PPE) when a known voltage source is not available for verification before tests are performed.

Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.
