功能說明
◎ MODEL 8800 SERIES DIGITAL/ANALOG FREQUENCY RESPONSE ANALYZER
The Venable Model 8800 Series is the first in our family of digital frequency response analyzers (DFRA) and our latest technology patent as the only FRA commercially available that can measure the plant of a digitally-controlled feedback loop directly and accurately.
The analyzer utilizes a digital “Sync” signal to provide synchronization between analog and digital hardware. The Model 8800 performs simultaneous analysis on both analog input channels and digital target processor, reliably capturing all data. Versatile by design, the Model 8800 digital interface can be disabled, via software, to use the analyzer in a standard 2-channel, analog-only configuration. Reliable and efficient by design, Venable Frequency Response Analyzers provide a direct connection to your DUT (Device Under Test), eliminating the need for additional external boxes and cables required with other instruments.
◎ MODULAR, SCALABLE DESIGN FOR SIMPLIFIED, COST-EFFECTIVE UPGRADES AND REPAIRS
Venable is the only manufacturer with its enclosure and internal architecture purposely designed for fast and cost-effective upgrades. While a 2 channel FRA may meet your needs today, increased testing requirements or new engineering projects may necessitate higher frequency range, more channels, which could mean a costly new instrument purchase. Not with Venable! Venable instruments are fully scalable, with a modular design that easily upgrades from 1,3,to 4 channels, increased upper frequency from 5.20 to 40MHz, or add a digital option to characterize the feedback loop of a digitally controlled power supply. Additionally,the modular design decreases repair costs, eliminating the need to replace an entire mother board for repair as is frequently the case with many FRAs.
◎ STABILITY ANALYSIS™ SOFTWARE
The 7400 Series includes Venable’s Stability Analysis Software, the next generation software from the creator of the K-Factor Technique. This full-featured software allows users to easily transfer data between plots, export data to and from other applications such as Excel® and MATHLAB, change sweep parameters during sweep, includes a simple SPICE-like program for modeling the AC frequency response of circuits, and is the only FRA software that has transfer math function.
◎ Z540.1 LEVEL II CALIBRATION
The Z540.1 Level II Calibration Certification is a requirement of most companies adhering to ISO 9001 Standards within their production facility. Venable is one of the only frequency response analyzer manufacturers that offers calibration to the higher standard, including data, in an ISO/IEC 17025:2005 Accredited Laboratory.
