September 15, 2009 – Albuquerque, NM – ZTEC Instruments introduces three new
series of high resolution 300 MHz bandwidth oscilloscopes in PCI, PXI, VXI and LXI
form factors. The new ZT4420 (12-bit), ZT4430 (13-bit), & ZT4440 (14-bit) series of
oscilloscopes are the fastest sampling oscilloscopes or digitizers available in PCI,
PXI, VXI and LXI at these levels of ADC resolution.

All instruments offer 128 Msamples of acquisition memory on each input channel.
The instruments can be interleaved for 256 Msamples maximum acquisition length
on one half the channels.
• The ZT4440 series has 14-bit ADC resolution and a maximum real-time
sampling rate of 400 MS/s per channel, or 800 MS/s max when interleaved
• The ZT4430 series has 13-bit ADC resolution and a maximum real-time
sampling rate of 250 MS/s per channel, or 500 MS/s max when interleaved
• The ZT4420 series has 12-bit ADC resolution and a maximum real-time
sampling rate of 500 MS/s per channel, or 1 GS/s max when interleaved

These oscilloscopes provide the same powerful triggering, acquisition, waveform
math, and analysis functions that are commonly found in today’s performance
benchtop instruments and that are found in ZTEC’s other M-Class oscilloscopes. In
fact, they can replace benchtop oscilloscopes in many ATE, aerospace, defense
and particle accelerator applications. The LXI instruments specifically are ideal for
applications requiring remote monitoring and control as well as for portable test
applications.

These powerful modular oscilloscopes are available in 2 channel models (ZT44x1
PCI, PXI, VXI and LXI) and in 4 channel models (ZT44x2 VXI and LXI only). With their
on-board processing, the ZT4420, ZT4430, & ZT4440 series calculate over 40
waveform parameters related to a waveform’s voltage, time and frequency
characteristics. Four calculation channels for performing basic and advanced math
on acquired data are also standard with each oscilloscope. Math functions include
add, subtract, multiply, integration, differentiation, FFT, histograms, measurement
trending and more.

These oscilloscopes accept a wide range of voltage levels, handling up to +/- 210 V
CAT I direct inputs. With input ranges from 1 mV/div to 1 V/div (10 vertical divisions)
for 50-ohm input impedance, and from 1.25mV/div to 5 V/div for 1M-ohm input
impedance, they cover a wide range of voltage levels without the need for external
signal conditioning (attenuators, probes, etc.). This is important in automated and
remote test applications where it is difficult or impossible to quickly add/remove
external conditioning.

Free instrument drivers from ZTEC help users easily integrate the ZT4420, ZT4430,
& ZT4440 series into ATE and embedded test systems. Drivers and programming
support are available for key programming environments including LabVIEW,
LabWindows/CVI, MATLAB, COM, Visual C/C++, Visual Studio and others.
Additionally, all oscilloscopes include ZScope™ control and display software and
the ZFind instrument locator and configuration utility. The intuitive ZScope™ soft
front panel application, with the look and feel of a benchtop instrument, gives users
complete control of the instrument and displays acquired waveforms, math
waveforms, and waveform parameter data. ZFind™ enables users to easily identify
what ZTEC instruments are installed on the current host and even share
instruments with other computers. ZFind™ also lets users send SCPI commands
to connected instruments and read back information from those instruments.
Prices for the ZT4420, ZT4430, & ZT4440 series start at $5,995 US.
