Synthesisers offer microwave migration
path
Anritsu has added three new CW generators to its MG3690A series, creating the industry's first synthesiser family to cover the entire DC to 65GHz frequency range.
Anritsu has added three new CW generators to its MG3690A series, creating the industry's first synthesiser family to cover the entire DC to 65GHz frequency range The three new models - the MG3691A, MG3695A, and MG3696A - maintain the high performance of the MG3690A series, including high spectral purity and frequency stability plus ultralow phase noise, and can be used in a variety of laboratory and production applications that previously required separate RF and microwave synthesisers

Bluetooth tester runs the lot in 10 seconds
Anritsu has introduced the MT8850A tester to offer manufacturers of Bluetooth modules comprehensive, one-button testing traceable to national standards.
Anritsu has also developed an IF up-conversion option for the MG3690A series that allows IQ modulation at microwave frequencies.
With this option, the MG3690A, when combined with an RF IQ-modulated source, can create IQ modulated signals up to 40GHz.
Previously, the highest frequency IQ modulation source only reached 6GHz.

Portable jitter analysis for SDH and SONET systems
Anritsu has introduced the MP1580A, a portable jitter analyser for 2.5/10Gbit/s SDH/SONET fibre-optic transmission systems.
The introduction of the three new synthesisers creates an easy migration path, allowing engineers to upgrade to microwave models when necessary.
The MG3695A (2-50 GHz) and MG3696A (2-65GHz) offer 50% more power than previous models at frequencies above 20GHz, delivering +3dBm.
Covering 2-8.4GHz, the MG3691A delivers similar performance at lower frequencies.
All the models in the MG3690A series achieve frequency resolution of 0.01Hz over the full frequency range and provide phase offset capability.
Anritsu has integrated a digital down-convertor (DDC) into the series to achieve full-band, ultralow phase noise.
The SSB phase noise of the MG3690A is -107dBc/Hz at 1kHz offset from a 6GHz carrier.
The models in the MG3690A series can act as CW sources of single RF and microwave frequencies or as digitally swept sources, sweeping either frequency or power, or both.
As a CW source, the generators feature as many as 20 independent markers to set independent CW frequencies.
When used as a sweeper, the synthesisers allow sweep widths to be set from 0.1Hz to 65GHz, with the optional direct digital synthesiser (DDS) installed.
The number of sweep steps can be adjusted from 10 to 10,000, with every frequency step in the range phase-locked.
A list sweep mode, which is controlled from the front panel or by GPIB, allows the MG3690A series typically to switch frequencies in approximately 10ms.
In this mode, as many as four data tables with 2000 nonsequential frequency/power sets can be stored in memory and addressed as a phase-locked step sweep.
The synthesisers can also perform a basic frequency-hopped or frequency-agile function via GPIB.
As many as 3202 data points of power or frequency can be stored and recalled from nonvolatile memory.
A COM-based interchangeable virtual instrument (IVI) driver is incorporated into the MG3690A series, making it suitable for ATE environments.
Further enhancing the series for rack applications is its compact 13.3cm package and its high output power that assures adequate signal strength to the device under test, even after ATE switching and cabling losses.
