The BK Precision 4040A Sweep/Function Generator combines multiple functions into a single, versatile signal source. It integrates waveform generation, pulse generation through variable symmetry, and frequency sweep capabilities, making it an essential tool for various applications. The built-in frequency counter enhances accuracy by providing precise output frequency measurements beyond what a simple calibrated dial can offer.
This function generator features coarse and fine-tuning controls, ensuring precise stability of the output frequency. The internal frequency counter, capable of measuring external frequencies, displays output signals between 5 and 30 MHz. Its broad functionality makes it suitable for both analog and digital electronics in engineering, manufacturing, servicing, education, and even hobbyist projects.
At its core, the function generator utilizes a voltage-controlled generator (VCG) that produces precision sine, square, or triangle waves over a frequency range of 0.2 Hz to 20 MHz. This wide range supports subaudible, audio, ultrasonic, and RF applications. A continuously variable DC offset allows direct circuit injection at the correct bias level, ensuring flexibility in testing and experimentation.
The sweep generator provides both linear and logarithmic sweeps, with variable sweep rate and adjustable sweep time. Front panel controls enable easy adjustment of start and stop frequencies. The burst operation function allows the output to be gated by either an internal adjustable signal or an externally applied one, adding further flexibility to signal modulation.
With variable symmetry control, the output waveform can be modified to generate rectangular waves, pulses, ramp or sawtooth waves, and slewed sine waves. The unit also supports amplitude and frequency modulation, which can be achieved using either a 1 kHz internal adjustable signal or an externally applied input. Additionally, an external voltage can control the operating frequency, making it ideal for situations requiring externally managed frequency adjustments.
By allowing multiple functions to operate simultaneously, the Model 4040A enables the generation of complex outputs, such as gated pulse trains with external or internal sweep. Its robust design and extensive feature set make it a valuable tool for a wide range of electronic testing and signal generation applications.
The BK Precision 4040A is used and reconditioned. Our technicians test all equipment to confirm that they operate properly and to the manufacturer’s specifications.
While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. Additionally, if you have specific testing requirements or requests, please inform us. We will gladly work with you to ensure these requirements are addressed during testing.
The photos above represent our equipment, which is currently stored in our warehouse. Since we often stock multiple units of each model, we may not feature photos of every unit. However, if you request, we will provide photos of your specific equipment after we test and clean it.

Yes, all equipment from American Instrument Exchange comes with a warranty.
Used/reconditioned/refurbished equipment is tested to make sure it operates to the manufacturer’s specifications and comes with a 90-day warranty (unless otherwise noted). New equipment comes with a warranty from the manufacturer.
Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly. While we may not be able to test for specific analytical applications we do our best to simulate the conditions under which the equipment will be used in your lab. If you have particular testing requirements please let us know and we’ll work with you to make sure these are addressed during testing.
We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS. Larger equipment will be palletized and shipped either LTL or air-ride, depending on the specific equipment and/or delivery requirements. In many cases we can offer inside delivery. Customers are also welcome to make pick-up arrangements using their own preferred carrier.
All shipments are FOB Haverhill, MA. American Instrument Exchange will take reasonable steps to protect the equipment during shipment and the equipment will be fully insured. The customer will be charged for all shipping and handling charges, and fees incurred in the process of delivering the order.
For local customers in and around New England we can offer shipping and delivery using a local moving company trained by our staff to handle and deliver lab equipment. Our local movers can provide either standard dock-to-dock delivery or bring the equipment into your lab and set it in place.
Prior to signing the POD (Proof of Delivery), you are responsible for inspecting the goods for any damage. You MUST note any damage on the POD prior to letting the driver leave. This is to protect you, the receiver of the goods in the unlikely event of any damage. Once you sign the POD free and clear from damage, the goods are then deemed delivered in good order and no further claims would be applicable. This is the standard for all transportation so we want to protect you, our valued client.
American Instrument Exchange will accept the return of any product that is not working as represented and could not be replaced or repaired to the customer’s satisfaction by American Instrument or a technician hired by/vetted by American Instrument Exchange’s during the warranty period. The customer will be responsible for proper packaging of the equipment and all included accessories.
Customers who cancel orders after refurbishing has begun or after delivery where there are no equipment performance issues will be subject to a cancellation and restocking fee of between 20% and 40% and responsible for the full total of the shipping & handling costs for both the delivery and the return of the equipment.
