The ZT4620 Series Digital Storage Oscilloscopes are available in VXI, CompactPCI/PXI, LXI, and PCI formats and come with the ZScopeTM GUI. Developed as an updated solution, the series provides a 3X reduction in rms noise over the ZT1428 and a 2X increase in bandwidth. Other ZT4620 features vs. the ZT1428 include FFT capability; deep and segmented multicapture memory; more measurements, waveform math, and acquisition modes; self-test and calibration functionality; advanced analog and digital triggering; and IVI, C/C++, PnP, LabVIEW, and COM drivers.

Key specifications include an input of 8-mVpk-pk to 50-Vpk-pk ranges, ±250-V offset adjustment; 10-S/s to 1-GS/s sampling rates; 2.5-GS/s to 100-GS/s equivalent time sampling rates; and a maximum capture length of up to 256 Msamples.

ZT4620 DSOs support total legacy instrument compatibility such as signal I/O and command interface.

Two VESA DisplayPort Test Adapters, female DP-TPA-R and male DP-TPA-P, maintain signal fidelity while providing phase-aligned access via 10 individual SMA connectors. A separate low-speed connector and cable carry the other 10 signals. Each side of the four differential data pairs as well as both conductors of a fifth pair for the auxiliary channel are broken out on 6-inch, 50-Ω cables. Intra- and inter-lane skew are specified as ±6 ps. Near-end crosstalk ranges from -40 dB at 13 GHz to -57 dB at 4.05 GHz assuming a single aggressor.

A separate Test Adapter Calibration Fixture with 6-inch and 3-inch through connections as well as 6-inch short, open, and load standards is used to de-embed the TPA from the DUT being measured.

The XL-GPS Time and Frequency Receiver generates time and frequency signals referenced to Coordinated Universal Time (UTC) and conforms to the European Union RoHS Directive. In addition to a built-in 12-channel GPS, the receiver has a standard 10-MHz output and pulse rates from 1 pulse-per-second to 10 mega-pulses-per second. A time code generator output accommodates synchronization of remote devices.

The XL-GPS features a high-performance oscillator, GPS receiver accuracy of <30 ns rms UTC, frequency accuracy to 1x10^-12, and an LCD front-panel display and keypad for configuration, control, and monitoring. A built-in Ethernet network port supports remote operation via telnet and SNMP monitoring. Local control is via a serial port, and an alarm output can drive an alarm monitoring system.

Option bays are available for an expansion module; an alarm relay; a 1-, 5-, 10-MHz frequency module; and a multicode time code module.

The WaveXciter Series of single- or dual-channel 2.1-GS/s, 12-bit arbitrary waveform generators creates waveforms at frequencies up to 1 GHz with 8-digit resolution and one-point granularity. The series also can be used as a full-featured standard, modulation, or pulse generator.

The WaveXciter provides separate or synchronized channels with 10-ps resolution, 1-GHz sine and 500-MHz square waves, and 16-M (32-M optional) waveform memory. Smart trigger enables trigger hold-off, detect, wait, abort, and restart. Other features include up to 4 Vpk-pk DC-coupled or ±5-dBm AC-coupled output paths; advanced sequencer for step, loop, nest, and jumps scenarios; built-in fast dynamic segments and sequences hop control; two programmable markers (positions, width and levels); two instrument synchronization to form a four-channel system; and remote LAN, USB, and GPIB interfaces.

The EX1200-7500 Module delivers 64 channels of digital I/O capability in an eight-port configuration. The I/O can be single buffered to provide real-time data access, double buffered for synchronized data access, or configured with other modules as part of the EX1200 autonomous scan list function.

Selectable output voltage levels range from 3.3 V to 60 V; the current handling capability is 300 mA. All clamping diodes and open collector channels are pulled up internally rather than on a per-channel basis. On-board memory is up to 1 MB, and data rates are up to 2 MHz.

The EX1200-7500 has LXI Class A capabilities. An embedded web interface provides virtual monitoring and control of switches and instruments without the need for third-party software.

Two series have been added to the company’s line of programmable AC power sources: the 31000A, with a built-in transient generator for power line disturbance and waveform synthesis for military and compliance testing; and the 33000, three-phase sources that supply an output voltage from 0 to 300 VAC.

The 31000A series provides output voltages to 600 VAC and frequencies to 1,000 Hz. Soft Panel software is available for control and data collection in laboratory applications.

The 33000 series features power output from 500 VA to 4,000 VA per phase and output frequency from 15 to 1,200 Hz for avionics, marine, and military applications. The AC+DC mode extends the output function to simulate abnormal situations such as the power line containing DC offset or fast DC transients.

An upgraded Model 860FC 60-MHz dual-channel DSO/DMM now includes a USB 2.0 host port, a 3.8” color LCD display, and real-time datalogging. It features Wavelink™ Software for remote control via a PC, a 125-kB record length for each channel, and a sampling rate up to 200-MS/s. The DSO/DMM also provides auto setup and horizontal zoom, a 2.5-GS/s equivalent sampling rate, dual-channel waveform math and FFT, a horizontal zoom function with auto setup, and 22 automatic waveform measurements.

The USB host port connects with a Flash memory drive. The 6,000-count DMM has a datalogger that records and plots the measurement values vs. time on the LCD for up to 20 days. It complies with CATIII 600-V standards and ships with a holster, two scope probes, and a rechargeable battery pack.
