8657B – Agilent

Description

Item #: 8657B

Manufacturer: Agilent
Series: 86xx

8657B by Agilent is a Synthesized Signal Generator in the 86xx series. 8657B features a Frequency Range of 100 kHz to 2,060 MHz and an Output Level of +13 to -143.5 dBm.

The HP Agilent 8657B Synthesized Signal Generator can join together modulation modes for AM/AM, FM/FM, and AM/FM from inner and outer modulation sources. AM is ac-coupled, whereas FM can be ac- or dc-coupled. Dc-coupling results in steadiness over an extended period and center frequency preciseness. However, when dc FM is active, SSB phase noise and residual FM performance are not reduced as is usual with other Signal Generators. In order for specifications to be accurate, there is a recommended 30 minute warm-up time, with an operating temperature range of 0 to 55 degrees C. This model encompasses a frequency range from 100 kHz to 2,060 MHz, weighs 45 lbs., has dimensions of 5.25 x 16.75 x 22.6 in., and a resolution of 1 Hz.

The 8657B Synthesized Signal Generator has the capability for pulse modulation when Option 3 is added. Option 3 provides a swift rise time and high isolation. Rise times are 35 to 50 ns (usually 10 to 18 ns), while on/off ratios have a range from 70 to 90 dB. If pulse modulation is only desired for coverage to 1,040 MHz, Option H60 can be ordered instead.

The Agilent 8657B can save 100 comprehensive instrument states. This feature reduces set-up time when completing repetitive assessments and decreases user mistakes. Since production lines need throughput that is quicker than before, test equipment has to be more dependable. Output level cycling needs electromechanical relays to switch in and out of attenuators to generate different output levels. The 8657B boosts system up-time with dependable attenuator technology.
