This Rare Fully Loaded HP (Agilent) HP (Agilent) 54300A Probe Multiplexer 2x8Channels is in very good physical and electrical condition. First – Sorry about the poor practices during testing. Each input of the system was tested on an oscilloscope with 100MHz/500MHz and 1GHz, And 100MHz/500MHz/1GHz/2GHz/3GHz/4GHz on a spectrum analyzer. The photos are combined uncertainty of the RG400 test cables and 54300A with the 54002A’s was pretty flat well past 1GHz and rolled off to about -3dB @ 3GHz and -5dB @ 4GHz. The RG400 BNC test cable loss appeared greater then the uncertainty of the 54300A. Please refer to the listing photos. This 54300A system consists of two/dual 8×1 Multiplexers and is fully loaded with 54002A 50ohm input modules. This auction also includes:1x 54300A Probe Multiplexer16x 54002A Pods2x 54001A 1GHz Active Probe Pods (in box with all accessories New) 2x 54003A 1 Meg Ohm Pods (one with 10X Probe and all accessories) The Keysight Agilent HP 54300A Probe Multiplexer is a programmable, dual eight-to-one probe multiplexer designed to expand the input capability of instrumentation with 50-ohm inputs. The unique strength of this multiplexer is its configurability. The user may select from three different input pods (sold separately): two high-frequency, high-impedance probes, or a 50-ohm BNC input for terminated line applications. The Keysight Agilent HP 54300A is ideal for delicate situations where high-frequency connections must be maintained and probes cannot be conveniently moved from one connection to another. Complex measurements can be automated by using the multiplexer’s 16 inputs, switching one or two of them at a time into the test instrument, under computer control. In situations requiring more than 16 inputs, multiplexers may be cascaded in series to give a total of 128 inputs. Features full HP-IB programmability as well as simple front-panel control. It also has non-volatile memory for storing lists of switching steps. Switch lists can be advanced step-by-step from a front-panel button, over the HP-IB or for data logging applications, through a TTL pulse entered at the rear panel. We have done our best too list this items specifications and condition accurately. But always defer to the listing photos. Concerning product details and specifications please refer to the manufactures website, or other online sources for more information such as data sheets, manuals, firmware updates, software, or reviews.

Please consider the total with shipping when bidding on items without free shipping. Our Company and Philosophy: We Want your purchase to exceed your expectations. The first question is whether this is the right piece of equipment to meet your needs, Feel free to ask for our expertise, we have no problem steering you to another eBay seller, dealer, or manufacturer who has exactly what you are looking. The second question is condition. In this case “As Is” “No Returns”. We have done our best to describe the issues, but please ask questions before you bid. We view others with a passion for Test and Measurement as part of a very special community whether a hobbyist or Noble Price level Physicist and will do our very best to treat any buyer the way we would like to be treated ourselves. All we ask is you treat us fairly and we will always go the extra mile even beyond eBays requirements and our stated warranty to take care of any legitimate issue – whether a performance issue or simply not the instrument that best serves your needs. Again we encourage you to contact us before you bid with any question on the capabilities, condition, and perhaps most importantly if it is the right product to meet your specific needs. About Us: Ascent Concepts and Technology (ACT) and our new Phoenix Metrology Research Group is a few scientists and engineers involved in R&D of Time and Frequency as well as Voltage Metrology Instruments intended to bridge the ever widening gap between Quantum Standards and current State of the Art calibration and measurement instruments. Basically a bunch of Test and Measurement nerds. We find buying and selling equipment a nice compliment to our R&D work. “To be is to do” Socrates. “To do is to be” Jean-Paul Sartre. “Do be do be do” Frank Sinatra…….Proof of de-evolution? International Buyers: Our official policy is no international buyers, If we make an exception please be aware buyers outside the continental USA are purchasing strictly “As Is” “No Returns” with no warranty expressed or implied International buyers must arrange their own shipping. Please contact us before bidding. International Buyers are responsible for all Duties, Vat, Customs, and any other Fees related to this sale. More detail on terms above: For any buyers outside the USA ACT will be glad to spend additional time testing before shipping, but we strongly encourage shipping to the Manufacturer or accredited calibration lab of the customers choice and expense (in the USA) to insure proper function before forwarding internationally. Obviously the customer is responsible for shipping from the testing/calibration lab and any costs related to testing or calibration. If the item fails testing we will pay return shipping from the calibration lab and provide a full refund of your purchase. Finally – To plagiarize Mark Twain “I apologize for such a long Listing – I didn’t have time to write a short one.” Please feel free to EMAIL Tom Knox or CALL: +1.303.554.0307 with any questions.
