3.3 GHz PXI RF Analog Signal Generator—The PXI‑5651 features continuous-wave generation capabilities with FM, 2‑FSK, or OOK modulation. It uses direct digital synthesis (DDS) for high-resolution frequency hopping or phase-continuous sweeping for fixture and device characterization applications. The PXI‑5651 is ideal for clocking nonstandard sample rates, such as WCDMA signals at baseband or intermediate frequency (IF). With these versatile signal generators, you can perform analog and digital modulation through the onboard DDS circuit, which gives you frequency modulation and frequency-shift keying for applications such as bit error rate test, antenna testing, or even keyless entry. You can also perform amplitude modulation using on-off keying.

Standard Electric Works Co., Ltd
● The 188FFF doesn't have the function of the sensitivity adjustment. If the customers need the sensitivity adjustment function, plase refer to other models.● The 188FFF is a Fuse and Fault Finder which comprises of two parts : The Receiver and the Transmitter.● The Transmitter, draws a current from the mains supply circuit to which it is connected to. The Signal● Current from the Tx is at about 10kHz. The Transmitter is powered by the mains and requires no batteries.● The 10kHz signal current generated by the Transmitter is then searched(sniffed) by the Receiver to detect the Fuse, Circuit Breaker or the faulty circuit.● The Receiver is a tuned circuit which has it's center frequency tuned to about 10kHz. The sensor is located in the tip of the Receiver.● The amplitude of the received signal is shown on a bar-graph type Leds.● The more Leds ON, the stronger the signal.

280X Series -
Vitrek Corporation
With an extended measurement range from micro-amps to hundreds of amps and millivolts to kilovolts, the 2801 & 2802 are the ideal analyzers for standby power or Energy Star testing. In addition to numerical results, the 2801 & 2802 captures waveforms with true 512-point precision. Results and waveforms can be displayed, read via communication ports or sent directly at full resolution to a USB printer. Power and amplitude measurements with an accuracy of <0.1% are automatically synchronized to the fundamental frequency. Peak, RMS, rectified and DC measurements of voltage, current and power are provided including continuous, inrush, startup and history modes, plus an integration mode for W-Hr, A-Hr, VA-Hr as well as integrated average power. (Channels can be operated synchronously or independently on the 2802). The 2801 and 2802 also provide waveform peak and glitch capture modes.

RA062-F2 -
Teledyne Defence & Space
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.

Techimp HQ S.r.L
New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

SDG7000A -
SIGLENT Technologies
SIGLENT’s SDG7000A is a family of dual-channel Arbitrary Waveform Generators that feature up to 1 GHz bandwidth, a maximum sample rate of 5 GSa/s, and 14-bit vertical resolution. It can generate arbitrary waveforms point by point with a maximum 2.5 GSa/s sample rate and vector signals with a maximum of 500 MSa/s. It also has the ability to generate a variety of signals such as continuous wave, Pulse, Noise, PRBS patterns, and a 16-bit digital bus. It supports the generation of complex signals such as modulation, sweeping, bursting, and dual-channel copying/coupling/tracking and superposition. The outputs are user selectable for differential or single-ended connections and support a maximum output range of ± 24 V. The instrument can ensure a large amplitude under high-frequency which eliminates an external power amplifier in some applications and addresses a wider range of requirements.

Fairview Microwave Inc.
The new MMIC IQ mixers from Fairview (also known as IQ modulators) utilize a highly reliable GaAs MESFET semiconductor process which integrates a pair of matched double balanced mixer cells, a 90-degree hybrid and a 0-degree splitter/combiner that produces exceptional amplitude and phase balance performance. This level of integration offers size and performance advantages in comparison to discrete module assemblies. With the addition of an external 90-degree IF hybrid module, these IQ mixers can be used as either a Single Sideband Up-converter Mixer or an Image Reject Down-converter Mixer. The benefit of image rejection and sideband suppression can reduce overall system cost and complexity by removing the need for pre-selection filtering. Typical applications include point-to-point and point-to-multipoint radio, VSAT, military radar, electronic warfare, satellite communications, test equipment, and sensors.

LS-45-DB -
Lumistar Inc.
The Lumistar LS-45-DB Dual Channel Bit Synchronizer Daughterboard provides optimal reconstruction of a serial PCM data stream that has been corrupted by noise, phase jitter, amplitude modulation, or base line variations. The all-digitaldesign assures a high performance, consistent product, with excellent reliability and long-term stability. Dual channel design can feed each channel of the LS-55-DD dual decom. The LS-45-DB also has a post D combiner that allows for optimal ratiocombining of the two input signals A unique Built-in-Test feature allows performance verification for the Bit Synchronizer to ensure the highest level of operation. Auto-test BIT is performed for a short duration on the application of power and tests more than 90% of the Bit Synchronizer components. This test verifies that power is properly applied, verifies that there are no internal bit errors, and performs other tests to ensure that the bit synchronizer is fully operational with status indication of results. Command-test BIT performs the same functions and can be initiated by the user at any time through the Lumistar software when used on Lumistar PC products. The user has the ability to generate internal pseudo-random patterns and calculate internal bit error rates with or without the injection of forced errors.Various status indicators are also available through the software. The Bit Synchronizer also contains a BER reader as well as frame sync pattern indicator.
