Description
An amplifier stage or a sensor front end needs a clean test signal before anyone trusts its results. The Tektronix AFG31051 function generator supplies that stimulus on one output channel, with sine up to 50 MHz. Lost in HCM lists it for rental and sale, so you can borrow it for a project or keep it on the bench.
Fine detail from a single channel
The generator samples at up to 500 MS/s and resolves 14 bits vertically. As a result, arbitrary shapes stay smooth instead of stair-stepped. Continuous sine starts at 1 μHz, so one box covers slow sensor drift and fast filter sweeps. The output impedance is 50 ohm, so match the load setting before you enable the output.

Memory you should name in the quote
Advanced mode comes with 16 Mpoints of memory per channel as standard. A 128 Mpoints upgrade also exists, but it stays out unless the quote names it. Therefore decide early whether long waveforms or sequences matter to your plan. Then list any accessories and calibration paperwork you expect.
Where one output earns its keep
This single-output model suits routine jobs, such as sweeping a filter to watch its roll-off. It can also drive an amplifier with a known input, because the stimulus repeats every time. In addition, it feeds sensor interfaces and other low-voltage circuits. The Tektronix AFG31051 function generator pairs well with an oscilloscope and a rated probe, so you can compare the circuit output with the stimulus.
Connect it safely
Check grounding, termination and signal limits in the manuals first. Never connect the output to mains or high-voltage switching circuits. Amplitude limits also change with frequency and waveform, so read the datasheet for your case. Treat any bench diagram as an example, not a service circuit.
Rent or buy through Lost in HCM
A rental suits a validation run or a short project, while a purchase suits a bench that sees daily use. In both cases, request a quote from Lost in HCM with your application, accessories and delivery site. You can also browse more waveform and function generators, read the Tektronix website or contact SMK Vietnam. Because Lost in HCM confirms each quote individually, name the Tektronix AFG31051 function generator by its model code.
AFG31051 questions
Does the AFG31051 have a second output?
No. This model has one channel, although the series photo may show a two-channel front panel.
How low can the sine frequency go?
Continuous sine starts at 1 μHz, so it reaches far below audio, and it tops out at 50 MHz.
Does the quote include the extra memory?
Only if you ask for it, because the 128 Mpoints upgrade is optional.
