Measurement Software for RF Power Meters
The 4530 series RF power meters and the model 4500A RF peak power meter/analyzer now include software that provides highly complex statistical analysis features for added capability in measuring power of next-generation wideband modulation scheme signals such as wideband CDMA, EDGE and third-generation. Designed for production automatic testing equipment, the 4530 series can measure signals from 10 kHz to 40 GHz (depending on the sensor) across a 20 MHz video bandwidth with an effective sampling rate up to 50 Msamples/sec for repetitive signals. The model 4500A operates over the 1 MHz to 40 GHz frequency range and can perform a number of measurements quickly with an effective sample rate up to 5 Gsamples/sec. The software features include statistical modes that provide users with the capability to fully analyze power distribution, including peak power over time, and a unique time gating capability to calculate average power for more accurate measurements of wideband signals. Price: starts at $3650 (4530 series) and $15,000 (model 4500A). Delivery: 12 weeks (ARO).

24-channel Noise Generator
The model UFX9736 modular, multichannel noise generator provides uncorrelated, time-varying, random noise signals for each channel, allowing realistic burn-in conditions to operate with every possible input signal level. The channels can be switched from noise to external signal input levels for testing with real data during burn-in channels. Designed for simultaneous burn-in and multichannel system testing, the unit features custom frequency ranges, a local keypad and a remote general purpose interface bus system control, two to 24 channel capacity, and module upgrades and additions to original systems.

Firmware and Calibration Kits
The Version 1.05 firmware and the models 3750LF and 3753LF calibration kits significantly improve the overall performance of the MS462x series vector network analyzers, which can perform error-corrected noise figure measurements on active devices used in wireless communications. The new firmware can display four active on-screen markers per channel and external voltages can be displayed and read via an analog input connector, thereby allowing voltages from ±25 V to be measured with external instruments. The calibration kits contain two precision male and female terminations, and one male and female open and short.

GSM Test Set
The IFR 2935/PhoneTest GSM test set includes an in-channel spectrum analyzer and an I/Q adjustment display. Designed for applications such as Go/Nogo test, mobile alignment and repair to final QA audit assessment, the unit offers improved level accuracy, SWR and power burst analysis. Optional software that provides maintenance and production facilities for mobile test and repair is available with the PhoneTest test set, giving users the benefits of a complete repair process solution.

The models 905 and 905R frequency counters are designed for on-site frequency calibration in automatic test equipment systems and calibration labs. Both models fulfill the requirements for calibrating cellular telephone base station master clocks with a short warm-up period of less than 10 minutes. These user-friendly counters feature a smart automatic input trigger control, plus an on-screen signal strength indicator to guide the user. Both models offer high resolution of 10 digits at one second measuring time and DC to 300 MHz standard bandwidth (up to 2.7 GHz optional). The 905R features a built-in Rubidium frequency reference and maintains a 50 times margin to base station master clock frequency accuracy specifications for 10 years without adjustment. Prices: $1695 (model 905) and $9995 (model 905R).

High Frequency Test Socket
The model 3750 high frequency test socket handler provides the clearance required for the Daymarc 717 plunge mechanism and alignment pins to mate with the handler. The lid assembly contains a compliant lead-backer that ensures contact with the company’s patented Microstrip Contacts™ on the board. (Use of the contacts results in a minimal contact self-inductance of 0.01 nH.) This pressure-mounted test interface fits all TSSOP-173 devices from 14 to 28 leads. Price: $2457.00. Delivery: six weeks (ARO).

RF Integrated Circuit Test System Software
The model 84000 series RFIC and IFIC test systems offer three standard configurations and new software that will improve time-to-market with target deliveries of eight weeks rather than three months and increase throughput up to 15 percent. The A.03.00 software provides incrementally expandable mixed-signal resources and measurement capabilities for meeting emerging production test needs. The test systems are capable of testing error-corrected S parameters and provide noise figure and power measurements on up to 12 RF ports. (Frequency coverage extends from 10 MHz to 3 GHz or 18 GHz.) The software also simplifies copying and pasting of multiple lines within a test plan to enable engineers to leverage entire sections more efficiently. Price (test systems): less than $500,000.
