PALO ALTO, Calif. Agilent Technologies has expanded its PSA series of spectrum analyzers with the release this week of the E4446A and E4448A models, which deliver frequencies up to the 50-GHz range and provide one-button power measurements for wideband CDMA, fixed broadband wireless, wireless LAN, and a host of wireless applications.
Almost two years old, Agilent's PSA series is targeted at design engineers looking for highly accurate instruments, and the release of the current third round of products is intended to keep that trend alive, said Dennis Handlon, product manager in Agilent's Wireless Business Unit.
The new instruments will deliver a -131-dBm sensitivity when operating at 44 GHz, a better than 10-dB increase in sensitivity versus competing solutions, Handlon said. The instruments also achieve a 3.27-dB amplitude accuracy at 44 GHz. Such accuracy provides designers with narrower test margins, which allows them to avoid rejecting products that sit close to the edge of a measurement band, Handlon said.
Both instruments are equipped with a 160-step resolution bandwidth and a 2-dB step attenuation. The former enables designers to optimize resolution bandwidth in their testing application to achieve faster sweep speed, Handlon said. The latter allows them to adjust power at the input mixer to optimize spurious free dynamic range, he said.
In addition to improving the accuracy of the instruments' measurements, Agilent also developed ways to ease the execution of difficult power measurements. The E4446A's and E4448A's enhanced power suite allow designers to match power measurements, such as adjacent channel power and multi-carrier power, to a particular application such as 802.11b, wideband CDMA, or Bluetooth, for example. Designers can now get an optimized power measurement for a particular application with the push of a button, Handlon said.
The PSA power suite also supports channel bandwidth, third-order intercept, harmonic distortion, burst power, spurious emission, and occupied bandwidth measurements. On the application front, it covers W-CDMA, GSM/Edge, 802.11a and .11b, HiperLAN2, cdmaOne, cdma2000 and Bluetooth.
The E4446A spectrum analyzer covers the 3-Hz to 44-GHz frequency range while the E4448A spans the 3-Hz to 50-GHz band. Both feature a selectable number of sweep points, and can deliver 1-millisecond swept measurements and 1-microsecond zero-span measurements.
Agilent said it is targeting the new spectrum analyzers at MMDS and 5-GHz wireless LAN applications. The company is also eyeing the instruments for LMDS and proprietary wireless backhaul designs, which generally operate at frequencies above 26 MHz.
The power suite options also make the E4446A and E4448A good options for emerging cellular designs, such as W-CDMA, Handlon said. Those options will also be supported in the 6-GHz, 13-GHz and 26.5-GHz versions of the PSA spectrum analyzers, he said.
The E4446A is priced at $68,000 and the E4448A at $79,000. Both are available now for delivery 12 weeks after receipt of order.
