Signal Generator features USB-controlled design.
Press Release Summary:
Offering tunable frequencies from 1 Hz to 100 MHz, TDDS100-48 Direct Digital Synthesized RF Signal Source features minimum of 0 dBm output power that is available from its SMA female socket. Laboratory-quality device can be swept in steps as low as 1 Hz between any two frequencies in specified range. Frequency changes are phase-continuous, so there are no glitches and phase noise is better than -140 dBc at 100 kHz. Second and third harmonics are below -60 dBc at 10 MHz.
Original Press Release:
Saelig Introduces Tiny TDDS100-48 Direct Digital Synthesized 1Hz-100MHz Signal Generator
Telemakus USB RF module gives laboratory-quality tunable frequencies from 1Hz to 100MHz.
Fairport, NY: Saelig Company, Inc. announces the availability of the USB-stick-sized TDDS100-48 - a laboratory quality Direct Digital Synthesized RF signal source with a frequency range of 1Hz to 100MHz and a minimum of 0dBm output power that is available from its SMA female socket. The TDDS100-48 is the smallest USB-controlled DDS synthesized source available and is priced significantly below other offerings. The high purity source can be swept in steps as low as 1Hz between any two frequencies in its specified range. Frequency changes are phase-continuous, so there are no glitches and phase noise is better than -140dBc @ 100kHz. Second and third harmonics are below -60dBc at 10MHz.
The unit also contains 0.5GB of flash memory used for installation files, test data, and other supporting documentation.   Current consumption from the USB2.0 interface is 200mA @ 5V. The TDDS100-48 is controlled using the provided easy-use graphical interface software which features both numeric entry and slider controls for setup and adjustment.Â
Applications include: local oscillator for frequency conversion, scalar measurements, pure tone reference signal, etc.  Two or more units can be combined for multitone testing. Use of an optional Telemakus hub allows the source to remain in a given state even after the host PC is removed from the system.Â
Made in the USA by Telemakus, a leading innovative RF design house, the TDDS100-48 Direct Digital Synthesized RF Signal Generator is available now from Saelig Company, Inc. Fairport, NY, Telemakus’ authorized US distributor.
