DS-3000 Microwave Synthesizer
Finest 20 GHz Signal Generator Available.
A World-Class Microwave Synthesizer
At Syntonic Microwave, our IFAT and RFT product lines required the very best in signal sources. Beyond what could be found on the market. So we set out to build the finest microwave synthesizer available anywhere. The result is our DS-3000, a truly ground breaking microwave synthesizer. The finest signal generator made today. And now, available to anyone.
High Performance and Reliability in Challenging Environments.
Designed and manufactured to be suitable for both commercial and military applications, the DS-3000 Microwave Synthesizer provides that perfect blend of low cost, high performance and high reliability in the face of challenging service conditions. So look to the DS-3000 when the application requires signal generator class electrical performance in difficult environments.

Your “do-everything” Signal Source and Clock
Syntonic Microwave’s DS-3000 Wideband Microwave Synthesizer is a state-of-the-art multi-loop synthesizer tuning continuously from 100 MHz to 20 GHz, in 1 Hz steps.
An RF Synthesizer for Demanding Environments
Phase noise and spurious performance is consistent with most demanding test equipment, receiver or carrier transmitter requirements. Tuning is accomplished via 4-wire SPI tuning or USB. The synthesizer includes an internal reference which will auto-lock to an external 10 MHz reference when present.

DS-3000 Signal Generator In-Depth
In this small, module package we have loaded:
- OUTPUT: Tunable in 1 Hz steps up to 20 GHz
- REFERENCE: Sync to External, Utilize for system clock
- I/O: SPI tuning, plus a Windows-based GUI
- DC SUPPLY: Power through Aux. DC Input or via multi-pin
- SYNC: Auto-senses availability of external REF
- LOW PHASE NOISE: Outstanding performance
High stability, low noise in a compact package.
The DS-3000 is designed to provide everything you need in a compact synthesizer. That is, excellent phase noise, from near-in offsets out to the very wide offsets. The high-stability, low-noise, accurate system clock (particularly in the DS-3002 “Ultimate” model) provides two separate outputs for sync’ing and daisy-chaining, enabling users to serve both 100 MHz and 10 MHz to adjacent, downstream and upstream equipment.
There are two ports for inputting DC to the DS-3000: one on a 14 pin multi-connector and the other on a separate DC input. This enables the DS-3000 to be powered quickly for benchtop operations, which means that just a DC connection and USB cable gives the user complete control instantly.
Locking connector mitigates shock and vibration
Alternatively, the 14 pin multi-connector can be used to power and control the DS-3000. A unique feature of the connector is locking hardware, which makes the DS-3000 suitable for rugged environments where shock and vibration may be present.
Multi-loop synthesis techniques are employed in the microwave frequency plan to give the DDS-based DS-3000 signal generator its excellent phase noise performance. Phase noise is further supported by the high quality, high performance system reference, giving users outstanding “near-in” phase noise characteristics. Excellent spurious suppression is a natural outcome of Syntonic’s synthesis methodology.
High speed internal switching guarantees fast tuning
Fast tuning is accomplished in the design through high-speed internal switching and settling. Plus, users are given a LIST MODE for pre-loading up to 5000 list entries for enhanced switching/settling through known frequency steps. List management is handled either directly, through the customer interfaces, or via external file (Excel, CSV) for convenience.
The User Experience of the DS-3000 RF synthesizer has been optimized to match the interface environment expected of today’s microwave signal generators. This includes an executable GUI running on a PC or laptop, a SPI machine interface for embedded applications, and 100’s of nuances that have been baked into the design which make using the DS-3000 satisfying for the user.
PHASE NOISE: A Detailed View
The DS-3000 is offered with two different phase noise profiles, the DS-3001 “Standard” version and the DS-3002 “Ultimate” version. The performance of the DS-3002 is geared for the finest in phase noise performance, particularly in near-in phase noise, at 100 Hz and 1 kHz offsets from the carrier.
Improved frequency stability is another feature of the DS-3002 Ultimate version. Details of the performance and differences are shown below.
