Semiconductor Optical Amplifiers
-
A Semiconductor Optical Amplifier (SOA) is essentially a laser diode (LD) with no feedback from its input and output ports and hence is also referred to as a Traveling-Wave Amplifier (TWA). Semiconductor Optical Amplifiers (SOAs) have proven to be versatile and multifunctional devices that are key building blocks for optical networks.

RF Milliwatt Meters
Type NDB-2 and NDB-3
-
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

Dual Channel HV Amplifier with Phase Inverter
A400DI
-
This unit contains two independent A400 amplifiers that share common ground reference and power supply. Please see A400 page for technical details.It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.

Multifunctional Safety Tests
-
Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line). Depending on the prescribed standard and directive, the following parameters are tested:- Leakage current and discharge current- Insulation resistance or the insulation strenth- Dielectric strength or electric strength- Correct installation of the protective conductor (ground continuity and ground bond test)- Faultless functioning of the product under the conditions defined for intended use (function or run test
