TPM-50A -
ShinewayTech
ShinewayTech@ TPM-50A Terminal Power meter can test (1) Average power range: -40 dBm~+20 dBm；(3) Modulation bandwidth: 5MHz；(3) Continuous signal and burst signal test. Highly accurate power measurement CW and digital modulated signal (For example: GSM/EDGE, CDMA/EV-DO, WCDMA/HSDPA, WiMAX, and TD-SCDMA). It is very important to test that if the transmitter is at a specified level or not. For example, the tester needs to test the output power of base station. Because the lower output power produces the larger coverage area to cause call interruption.

DPNA-6G AXIe -
Holding Informtest
The AXI DPNA-6G module is the world's first network analyzer in the form factor of the AXIe-1 module, as well as the first Russian device that meets the AXIe-1 standard. In the mode of the network parameters meter, the AXI DPNA-6G module measures the vector values of the network parameters on two ports: transmission coefficients (S12, S21) and reflection (S11, S22). At the same time, all necessary types of calibrations are supported: one- and two-port short-circuit, XX, matched load, transmission normalization. The software supports the import of third party calibration standard parameters. In the measuring receiver mode, the module provides:*generation of a harmonic signal (frequency synthesizer);*spectrum analyzer and power level in a given band;*measuring the frequency of a known signal;*measurement of analog modulation parameters;*phase noise measurement.

CNG-EbNo -
Noisecom
The CNG-EbNo is a fully automated precision signal to noise (AWGN) generator that sets, and maintains a highly accurate ratio between a user supplied carrier and internally generated noise, over a wide range of signal power levels and frequencies. The internal AWGN meter provides repeatable SNR waveforms for accurate signal generation. The instrument gives system, design, and test engineers in the telecommunications industry a single tool to generate precision signal to noise ratios. These signals are used to compare theoretical BER to SNR ratios, found in "waterfall" type graphs, with measured values from the DUT to evaluate different modulation schemes. Users can obtain higher yield through automated testing, plus increased confidence from repeatable, accurate test results. Standard units can be modified for specific customer requirements. Please consult the factory for pricing and availability of these requests.
