 Products Oct 1, 2004 12:00 PM Test and Measurement
Active probe
Tektronix Inc. has introduced the P7380 Differential Probe with Z-Active Architecture, a hybrid approach comprises a distributed attenuator topology feeding an active probe amplifier. The P7380 has an interchangeable passive probe tip. In addition, the P7380 provides high dc resistance and ac impedance for 1 GHz to 8 GHz frequencies. Digital test pod
CWAV has added the USBee SX digital test pod to the USBee product family. CWAV has designed the USBee SX system to take advantage of already existing PC resources. The USBee SX pod streams data over the high-speed USB bus to and from the PC, allowing the PC to perform all of the triggering and data storing. The USBee SX digital test pod can use available PC memory as the sample buffer, allowing selectable sample depths from one to many hundreds of millions of samples. Included in the logic analyzer module that runs on the USBee SX is an I2C, SPI and Async serial bus decoder that can extract the data from these buses from your captured traces. The USBee SX digital test pod can capture and generate up to a maximum of 24 million samples per second depending on the PC configuration. Modulation analyzer
Yokogawa has introduced a modulation analyzer capable of providing analysis of BPSK, QPSK, p/4QPSK, OQPSK, 8 PSK, 16 QAM, 64 QAM, 256 QAM modulation over the RF input frequency range of 84 MHz to 6.2 GHz. The memory is 128 Mpoints/ch. The analyzer consists of both time and frequency domain analysis. Options for 12.5G BERTS
Anritsu has introduced new options for its 12.5G bit error rate test set (BERTS) that evaluates high-speed devices used in storage area networks (SANs) and 10G Ethernet applications. The 12.5G BERTS consists of the MP1763C pulse pattern generator (PPG) and the MP1764C/D error detector (ED). It supports STM-0/STS-1 to 10G Ethernet, STM-64/STS-192 and OTU-2. The test sets feature a ¼-speed differential option that allows differential output of data and clock at a rate of ¼ of the standard 50M to 12.5G output. In addition to analyzing high-speed devices in 10G Ethernet, the differential option enables the 12.5G BERTS to analyze high-speed buses and backplanes, such as PCI Express, cheaper than using parallel BERTS, Anritsu claims. The clock/data recovery (CDR) option allows input data to be used as a trigger signal for error rate detection and waveform monitoring; an external clock or CDR isn't required. When the CDR option is used jointly with the new differential input option, high-speed differential devices can be evaluated without an external jig. The CDR is variable and supports bit rates from 62.5M to 11.1G, including 4.25G Fibre Channel. The MP1763C PPG with ¼ differential outputs costs $93,000; the MP1764D ED, which includes both differential input and variable CDR options, is priced at $127,000. Arbitrary waveform generator
Agilent Technologies Inc. has introduced a wideband arbitrary waveform generator (AWG) that delivers 1.25 GSa/s and 15 bits of vertical resolution simultaneously. The Agilent N6030A provides dual differential output channels to drive single-ended and balanced designs. Each independent channel is with 500 MHz of instantaneous analog bandwidth and more than 65 dBc of spurious free dynamic range. Combining the N6030A with Agilent's PSG vector signal generator gives designers 1 GHz IQ bandwidth for simulating IF and RF subsystem tests at microwave frequencies. The Agilent N6030A has 8 MSa or 16 MSa optional waveform memory for storage of arbitrary and complex waveforms. The Agilent N6030A arbitrary waveform generator price starts at $50,000. Optional waveform memory expansion to 16 MSa (N6030A-016) is $10,000. Both are expected to be available in November. RAID storage
Aeroflex Inc. has developed a storage capability for the Celerity CS35000 broadband signal analyzer (BSA) systems and the CS25000 broadband signal generator (BSG) systems. The enhanced capability can be added to any new or existing BSA or BSG test system. The RAID (redundant array of independent devices) storage capability can provide more than one Tbyte of disk storage space to the BSA and BSG systems with data transfer rates of 250 Mbytes/sec. These RAID systems can be used to store data files for fast download to BSGs for playback or for uploads from BSAs. Two modes of RAID operation are available. The streaming mode allows the BSA/BSG to act as a streaming recording or playback system, achieving sustained record or playback rates of 250 Mbyte/s for up to an unprecedented two hours.

GaAs MMIC feedback oscillator
Mimix Broadband, Inc. has introduced a gallium arsenide (GaAs) hetero-bipolar transistor (HBT), monolithic microwave integrated circuit (MMIC) voltage controlled feedback oscillator (VCO), which uses an on-chip filter to provide the necessary oscillation conditions. The circuit consists of a linear Lange coupled phase-shifter, a Lange coupled quadrature generator, a differential amplifier, a four-quadrant I/Q modulator and an output buffer differential amplifier. In addition, this device contains a frequency divider (divide-by-four) for phase-locking and an output buffer amplifier. From 5.5 to 8.4 GHz, this VCO achieves +4 dBm fundamental output power and +1 dBm divide-by-four output power. Mimix performs 100 percent on-wafer DC and output power testing on the 9OSC0315, as well as 100 percent visual inspection to MIL-STD-883 method 2010. The chip also has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. Engineering samples are available today from stock, and production quantities are available six to eight weeks ARO. LVPECL translator clock ICs
Pericom Semiconductor Corporation has launched a family of 3.3 V, 1:4 LVPECL clock buffers with speeds up to 800 MHz. The PI6C4853x IC's target the networking/telecommunications, storage, and industrial system markets. Due to the variety of high-speed applications using LVPECL clock signals and other differential signals, most engineers need to design around mixed-signal architectures, the company says. PI6C48533-01 (Differential to LVPECL), PI6C48535-01 (LVCMOS to LVPECL), PI6C48535-11 (Crystal to LVPECL) are suitable solutions for solving translation requirements as well as eliminating jitter concerns. Pericom's PI6C4853x-xx products are 3.3 V high-performance differential clock converters with four pairs of LVPECL outputs. Each device has different input signals to convert and Fanout to four LVPECL outputs. In addition, each device offers a selection of two inputs for systems with fail safe and redundancy requirements. Some systems distribute a clock signal from board to board, so if the main system clock fails, the local (backup) clock will be switched over to continue the operation. Dynamic clock switch
Exar Corporation has added a family of Intelligent Dynamic Clock Switch (IDCS) products. Exar unveiled the first two devices (XRK79993 and XRK79892) of a larger series of IDCS products. The XRK79993 and XRK79892 are cost-effective, low-skew 400 MHz clock generators for applications with redundant clock tree requirements that are capable of generating five LVPECL outputs from two LVPECL inputs. Two of the output pairs regenerate the input signal frequency and phase, while the other three pairs generate 2x (for XRK79993) and 4x (for XRK79892), phase aligned clock outputs. Whenever the built-in IRCS detects a failure on one of the two clock inputs, it automatically switches the PLL reference clock to the other input while minimizing the output phase transient. Additionally, the external PLL feedback can be used to provide zero delay buffer performance. The XRK7993 and XRK79892 Dynamic Clock Switch (DCS) circuit continuously monitors both input CLK signals. If the primary clock fails, the DCS will switch to a secondary clock, completing phase and frequency alignment with minimum output phase disturbance. This process eliminates the typical phase bump caused by a failed clock signal. In 1000-piece quantities, for commercial temperatures the XRK79993 is $8.75 and the XRK79892 is $8.75. Samples of the XRK79993 and XRK79892 are available now in 32-pin, LQFP packages.
