Differential Phase-Shift Keying

product
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.

Differential Voltage Probes
DP150/DP200pro
The DP differential isolation probes are an important accessory for any laboratory involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, whilst the oscilloscope can remain grounded. Using a DP150 or DP200pro probe, differential and floating measurements can be made on a variety of ac power systems like 230V/110V ac input power supplies, chopped and switching power supplies, thyristor controllers, variable speed motor drives (PWM signals), motor inrush current and measurement across current shunts. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope. The DP probes can be powered from a 9V battery or external power supply.
