The Venable Model 350c is the 3 channel successor to the original workhorse Model 350a/b that launched in 1986 and established Venable Instruments as a market leader. The contemporary 350c Series incorporates a 3rd channel, allowing the user to measure more transfer functions simultaneously with one sweep, such as source and load impedance. The 350c is the only frequency response analyzer in the industry that can measure absolute phase, using a reference channel.
All Venable instruments have built-in floating oscillator and channel isolation to 600VpK, eliminating the need for additional injection transformers or voltage reduction probes that are required with other frequency response analyzers. Connecting ancillary components increases the probability for more points of failure during the testing process, or worse, faulty results. 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.
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.
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.
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.
All Venable instruments with the current version of Stability Analysis TM Software supports Microsoft Windows XP Service Pack 3 and Windows 7, 8 and 10.
