ZTEC
Instruments (http://www.ztecinstruments.com),
recently introduced their newest addition to their ZProtocolTMsoftware suite. ZProtocolTM DPD (Digital Pre-Distortion) is a comprehensive digital
pre-distortion (DPD) software toolkit for Power Amplifier (PA) characterization
and testing.
Many of
the latest WLAN transceiver chip-sets employ DPD techniques to improve PA
linearity. The DPD software toolkit is used to quantify improvements in
spectral mask and EVM (Error Vector Magnitude).
“A
significant amount of pressure is placed on PA designers regarding EVM
contribution for 802.11ac devices. By using ZProtocolTM DPD with our RF test sets, designers can validate to their
customers true PA performance” says Christopher Ziomek, ZTEC’s president. “The
DPD software tool and corresponding example code provides a quick and easy
method to evaluate DPD for a PA or transmitter design. In combination with our
6 GHz vector signal analyzer (ZT8651) and 6 GHz vector signal generator
(ZT8751) that have respectively 160 MHz of instantaneous bandwidth and 500 MHz
of modulation bandwidth, our customers can characterize and test DPD for 802.11
ac 80 MHz devices” adds Ziomek.
ZProtocolTM DPD is used in conjunction with ZProtocolTM WLAN and is available for purchase today.
About
ZTEC Instruments
ZTEC Instruments believes that the future of test and
measurement requires tightly integrated instrumentation and computing
solutions. This combination facilitates the current trend toward shorter
development times, increased flexibility, lower cost, and smaller size in test
and measurement systems. We believe the future of test and measurement lies in
reliable, future-proof modular instruments. ZTEC offers modular RF, digital
storage oscilloscopes, and waveform generators using the PXI/PXIe, VXI, LXI and
PCI platforms. These are well suited to automation. For more information about
