The spokesperson said it surpasses the measurement capabilities and signal fidelity of both conventional high-voltage differential
probes and acquisition systems that rely on galvanic channel-to-channel and channel-to-ground high-voltage isolation.
Tenders are invited for supply of High-voltage Differential
Incorporating a high-voltage differential
amplifier stage and a high-current driver, the SM8-packaged device ensures that the MOSFET performs the same function as the diode it replaces, sensing the point at which the secondary current reaches zero.
The market decided that the robust, yet costly High-Voltage Differential
(HVD) or the limited distance, low reliability connections offered by Single Ended (SE) signaling were simply inadequate to serve the SCSI market moving forward.
Super DLTtape drives will support either Wide Ultra2 SCSI (80MB/second) Low-Voltage Differential (LVD) or High-Voltage Differential
(HVD) interfaces, depending on library model.
Ken Johnson, director of marketing and product architect, and Jeff Krauss, applications engineer, both at Teledyne LeCroy, described the HVD3605 high-voltage differential
probe (Figure 1) introduced in July as an addition to the company's HVD differential probe series.
The Terminator supports only LVD SCSI drivers; it does not support single-ended (SE) and high-voltage differential
(I-IVD) SCSI drivers (EIA485).
In addition, HP DLT Autoloader 818 customers have the option of a new low-voltage differential SCSI (LVDS) controller that interfaces with new-generation PC servers, as well as the high-voltage differential
SCSI (HVDS) controller for use with high-voltage SCSI host bus adapters.
A High-Voltage Differential
(HVD)/SCSI bus option is also available.
The DLT 8000 will be offered with options for both Single-Ended/Low-Voltage Differential (LVD) interface option and High-Voltage Differential
(HVD) SCSI interconnect to support of broad range of system options, including longer cable lengths.
This addition complements previously introduced high-voltage differential
and single-ended models by providing an all Low Voltage Differential (LVD) Ultra SCSI version.
More cost effective than high-voltage differential
, Ultra2 solutions are available now at prices ranging from $1,140 to $3,845 SRP.
