On the hardware side, the high-res mode has been improved (up to 52 dB of noise reduction on single acquisitions). Unlike Windows-based scopes, the DLM6000 boasts hardware-accelerated measurement parameters, user-defined math channels, and serial bus analysis. The five base models offer 6.25 Mpoints/channel and 16 or 32 logic inputs.
Prices for the DLM6000 start at $12,250.

The Infiniium 9000 Series oscilloscopes are engineered for today's broadest measurement needs. The instruments offer superior scope specifications and extensive application support, and in addition, the three-in-one instrument includes logic and protocol analysis capabilities. Agilent says this is the first scope to support PCIe and USB protocol analysis and that the family boasts the most advanced and easiest protocol analysis capability of any scope
The Infiniium 9000 family consists of mixed-signal and digital models with analog bandwidths of 600 MHz, 1 GHz, 2.5 GHz, and 4 GHz. With these highly configurable instruments, users can select the features and price points that best match their needs. Each model, equipped with a large 15-in. XGA LCD screen, comes in a whisper-quiet, highly portable package that is just 9 in. deep and weighs only 25 lbs.
Prices start at $17,500.

As bus speeds increase in frequency and type, the need to visualize multiple digital buses of gigabit speeds simultaneously while performing analog debug beyond 4 GHz is critical. To meet this need, the MSO70000 Series mixed-signal oscilloscopes combine the signal visibility and timing features of a high-performance logic analyzer with the analog precision of a high-performance real-time oscilloscope.
The instruments have up to 20 channels of measurement capture (4 analog and 16 logic), an analog bandwidth ranging from 4 to 20 GHz, and an 80-ps digital channel timing resolution. Tek says the MSO70000 is the ideal debug and verification tool for designs containing high-speed signals, like DDR memory, high-performance ASICs, FPGAs, system-on-a-chip devices, and digital RF. The soldered-in probe accessories make connecting to vias and fine pitch components on tightly packed boards easier, and an iCapture feature provides analog views on any connected digital channel.
Prices start at $67,400.

The PS9211 oscilloscope is based upon the company's PS9201, adding integrated clock recovery and an Ethernet connection. Integrated clock recovery of rates up to 2.7 Gbps allows engineers to view several signals(”SONET/SDH (OC1/STMO, OC3/STM1, OC9/STM3, OC12/STM4, OC18/STM6, OC48/STM16, and FEC2666), Ethernet (Gb and 2x Gb), and Infiniband (2.5 Gb))”with ease, while the addition of a Ethernet connection allows the unit to be controlled and viewed from multiple computers simultaneously or and also permits its use in a remote location.
The goal for all products developed by Pico is to be significantly lower cost with similar or higher specifications than those from other manufactures. The PS9211 continues this tradition. Pico says that while traditional bench sampling scopes have a price similar to that of a full-sized SUV, the PS9211 allows corporations to be able to afford specifications that get the project done.

LeCroy says that its WaveMaster 830Zi is the first and only oscilloscope to achieve a real-time bandwidth of 30 GHz. This oscilloscope provides engineers dealing with jitter, serial data integrity, and other high-frequency test challenges a sampling rate of 80 Gsamples/s on two channels and a maximum acquisition memory of 512 Mpoints/channel. The WaveMaster 830 Zi de-embeds cables and test fixtures, emulates serial data channels, and simulates serial data receiver equalization even at sampling speeds of 80 Gsamples/s.
Senior level design engineers who verify, test, and debug serial buses of 3 Gbits and above, working with high-speed serial data standards such as SAS/SATA 6, PCIe Gen3, HDMI 1.3, and USB3, need speed and efficiency. Exceptional instrument responsiveness; 10 to 100 times faster processing throughput; a large 15.3-in., 16:9 high-definition touch-screen display; and both 50-Ω/1-MΩ input capability provide deeper insight, faster debug, and more efficient validation.

The ZT4420 (12-bit, 1-Gsample/s), ZT4430 (13-bit, 500-Msamples/s), and ZT4440 (14-bit, 800-Msamples/s) oscilloscopes are the fastest sampling oscilloscopes or digitizers available in PCI, PXI, VXI, and LXI at these levels of ADC resolution, according to ZTEC. The company says the oscilloscopes provide the same triggering, acquisition, waveform math, and analysis functions that are commonly found in bench instruments at approximately 60% of the cost. They can replace bench oscilloscopes in many ATE (automated test equipment), aerospace, defense, and particle-accelerator applications.
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-Ω input impedance, and from 1.25 mV/div to 5 V/div for 1M-Ω input impedance, they cover a wide range of voltage levels without external signal conditioning. ZTEC says that no other product offers this combination of speed, resolution, and voltage range.
Prices: $5,995 to $14,995.
