PERFORMANCE WITHOUT PEER
Anritsu’s 69000B series utilize
state-of-the-art technology to
deliver extremely low SSB phase
noise. These units are ideal as
low-jitter clocks, references for
LASER and other optical
applications, and in high-bit-rate
digital modulation systems where
low phase noise is a critical
specification.

Automatic Test Equipment
The Anritsu 68C/69B series are your best choice for A.T.E.
applications. They pack the highest performance available in
a single 13.3 cm package to minimize rack space. High output
power assures adequate signal strength to the device under test
even after A.T.E. switching and cabling losses. Accurately leveled
output power to –120 dBm in 0.01 dB steps facilitates receiver
sensitivity measurements. Fast 5 ms switching time maximizes
system throughput. Internal list mode frees the A.T.E. controller
to perform measurement analysis tasks. Optional SCPI
programmability and free application drivers, including the IVI-
COM driver and National Instruments LabView
® drivers, save
you time and money in code generation and maintenance.
One-box, Ultra-clean RF and Microwave Signal Solutions
The Anritsu “El Toro” synthesizers are now available with the new ultra-low phase noise Digital
Downconverter. The new DDC offers ultra-low SSB phase noise in the 10 MHz to 2.2 GHz
frequency range, where the highly congested communication bands require extra clean signals.
The DDC phase noise performance is typically 30-50 dB better than other microwave synthesizers
and comparable to the best RF synthesizers in the market.
The Digital Downconverter produces 10 MHz to 2.2 GHz signals by successive binary division of
the synthesizer’s microwave drive signal, so the DDC does not introduce non-harmonic spurious,
which is a problem in mixer-based downconverters. Also, phase perturbations of the carrier are
reduced with each successive frequency division, so phase noise decreases as the output
frequency is decreased.
Now with the new DDC, Anritsu synthesizers are true one-box solutions for ultra-clean RF and
microwave signal generation, offering outstanding performance in applications that previously
required a separate RF synthesizer.
