  • Model 2810 RF Vector Signal Analyzer
Nov 2006
Keithley Instruments Inc.Request Info
CLEVELAND, Ohio, Nov. 1, 2006 -- Keithley Instruments' model 2810 radio frequency (RF) vector signal analyzer is optimized for automated testing of wireless devices and transmitter circuits in production test environments as well as in new product and device research and development. It features measurement speeds up to three times faster than competitive instruments in production test, takes up half the space and costs half as much as competitive products, the company said.

It is designed to work closely with Keithley's model 2910 RF vector signal generator for testing active and passive RF components. For example, production test engineers can use built-in list mode features with the test modes of the latest mobile phone chipsets to perform fast simultaneous calibration of the phone's transmitters and receivers, dramatically reducing test times Keithley said.

The analyzer uses an advanced software-defined radio architecture with a 500-MHz digital signal processor, enabling fast data acquisition and processing. Production test engineers can drastically reduce test times, while R&D engineers and scientists can reduce the time it takes to acquire large sets of data. For example, in the case of users searching for spurious emissions from devices under test, the model 2810 can perform a 200-MHz span sweep using a narrow resolution bandwidth of 100 Hz in approximately 15 seconds. A conventional spectrum analyzer needs 1000 times longer to perform the same sweep.

The model 2810's processing power is greater than 30 MHz of 3 dB measurement bandwidth with 20 MHz of flatness within 1 dB. Wide bandwidth signals can be captured in one acquisition, which is essential for capturing the new high-bandwidth, high-throughput transmission signals such as WLAN and WiMAX signals.

In addition to being able to decompose a waveform into its constituent frequencies, it can also decompose digitally modulated signals into their I and Q phase components. With the I and Q components, a vector signal analyzer can determine the quality of a modulated signal. Research and development personnel working with modulation schemes can easily transfer the acquired signal components to a PC for more extensive analysis.

The Model 2810 offers firmware options at prices significantly lower than competitors to enable more cost effective modulation quality analysis on GSM and EDGE signals, cdma2000 reverse-link signals and WCDMA uplink signals, Keithley said. A suite of GSM/EDGE measurements including time mask conformance, phase error or EVM, and channel power can be acquired and computed in 27 msec.

New modulation analysis schemes and new measurement algorithms can be incorporated with ongoing firmware updates, Keithley said. The analyzer has only two buttons and an intuitive touch screen and can be easily operated using a USB mouse, making it a suitable tool for communications theory training in student labs. The GUI uses a Windows-based display format, so any user who is familiar with operating a PC can easily navigate through the menus, and eliminates the need for an entire front-panel array of buttons,saving rack space in production and R&D environments.

Electronic attenuation, pre-amplifiers and a sweeping continuous wave source are included as standard features on the model 2810, which includes a three-year warranty at no additional charge.

The model 2810 includes three standard interfaces to meet current and future system integration requirements. An IEEE-488 interface enables users of legacy systems to easily integrate it into their test systems. Users looking for higher data transfer rates can use the USB or LAN interface. The LAN interface is compatible with the LXI-C standard.

The model 2810 RF vector signal analyzer is priced at $15,500. Several different signal analysis options are also available, starting at $1500.
