The model 4001 ultra-variable pulse generator is uniquely designed to permit precise tailoring of pulse repetition rates and duty cycles over a wide range through the independent setting of pulse width and pulse spacing. Both pulse width and pulse spacing are continuously variable over seven decade ranges from 100ns to 1s, with outputs from 0.5Hz to 5MHz. Its uncomplicated, rugged design and high quality components help ensure long and dependable service. Notable features include two simultaneous independent outputs (TTL and variable) with rise and fall times less than 30nsec, 20nsec TTL compatible leading-edge sync pulse output, and independent pulse width and pulse spacing controls (both selectable from 100nsec to 1sec). Four front panel push-button selectable operating modes with one-shot push-button can be used to produce pulse train or enable a single output pulse. Pulse duration is determined by width control. All of these features, plus an uncomplicated front panel layout all add up to an effective solution to a wide range of pulse source problems. The 4001 pulse generator with its many features and ease of operation make it a welcome addition to any lab. Some of the varied uses for the 4001 are as a missing pulse detector, tracing digital logic flow, analyzing microprocessor programs, or testing radio control receivers. The 4001 can also be used in audio testing and for many other applications requiring a precision pulse source. Variable output for CMOS circuits. Sensitivity: trigger/gate, DC couples, BNC connector, TTL compatible 40nsec wide, >2.4Vpk or sine wave >1.7Vrms. Outputs: 3 outputs, DC coupled, BNC connector. VAR impedance: constant 50 ohms. VAR amplitude: 0.5-10V into open circuit, 0.25-5.0V driving 50 ohms, variable with Amplitude control, rise/fall time less than 30 nsec. TTL drive: standard TTL levels, buffered to drive up to 40 TTL loads, rise/fall time less than 20 nsec. THE SIMPLE, NO HASSLE, NO B.S. WARRANTY This generator was tested 5/7/15 and was in working condition. If this item fails within 30 days of receipt at your location, please contact me for an RA number and ship it back. When I receive it back, I will refund your purchase amount, EXCLUDING $8 for the original shipping cost. My goal is 100% customer satisfaction, each sale, every sale.

YOU MUST HAVE A CONFIRMED ADDRESS TO PAY WITH PAYPAL! SHIPPING TIMES AND TERMS, INSURANCE RULES, SALES TAX, CUSTOMS Shipping quotes are for US customers in the 48 contiguous states only; there may be an additional charge for shipping to Alaska Hawaii or Puerto Rico. If you need an advance or overseas shipping quote just email me your zip code or address. If the S&H amount is not quoted as a flat rate, and you are a US customer, please use the shipping calculator provided by eBay to determine the shipping and handling charges to your home or business. Picking up your item is unfortunately not an option unless it is something that will require a trucker to ship. I realize it is nice if you are local to be able to save the shipping costs, but my work schedule is such that it is almost impossible for me to meet someone at the warehouse, and I do not do business from my home. All buyers must pay 7% NY State sales tax on all items shipped to a NY State home or business address or picked up at my warehouse. I am aware of my overseas customer's tax situations regarding VAT and customs duties. I record an accurate value on all customs forms, and am very careful not to include the shipping and handling amounts. By declaring the value of the item to be the exact high bid price, I ensure legal compliance and honest, accurate reporting for both of us.
