HUM DETECTOR (DEMODULATOR)
HD-500
-
Matrix Test Equipment Incorporated
The MATRIX Model HD-500 is a detector-amplifier designed to demodulate the low frequency amplitude modulations on any RF carrier over the range of 5 to 1500 MHz. These modulations are usually the undesirable result of the 50 or 60 Hz power source and are not necessarily sinusoidal. The unit is calibrated to the SCTE definition of hum modulation, which is the ratio of the peak-to-peak hum modulation to the peak of the carrier.

Modulation Distortion Up To 70 GHz
S930707B
-
S930707B enables fast and accurate active-device modulation distortion characterization under modulated stimulus condition up to 70 GHz. The wide dynamic range and vector error correction of the PNA-X result in an extremely low residual EVM of the test setup, so you can get a complete picture of your device’s performance without test system interference. S930707B can measure EVM, NPR, ACPR, and can decompose nonlinear signals and linear signals with the spectral correlation between input and output spectrum without doing demodulation. Integration with the PNA-X SCCM provides quick modulation distortion measurements while making other VNA measurements.

DQPSK Demodulator
-
Differential Quaternary Phase-Shift Keying (DQPSK) is the four-level version of DPSK. DQPSK transmits two bits for every symbol (bit combinations being 00, 01, 11 and 10) and has an additional advantage over conventional binary DPSK. DQPSK has a narrower optical spectrum, which tolerates more dispersion (both chromatic and polarization-mode), allows for stronger optical filtering, and enables closer channel spacing. As a result, DQPSK is the only modulation format which allows processing of 40Gb/s data-rate in a 50-GHz channel spacing system.
