A function generator xr2206 kit is a builder-level waveform source. LinkScope Sourcing 56 treats it as its own procurement line so it is not priced against a calibrated bench generator. The console below is the bill a training lab, a repair bench, or a student workshop should finish before factories reply.
| Console field | Buyer writes | Supplier answers |
|---|---|---|
| Oscillator family | XR2206 or a named substitute | Exact IC marking and board revision |
| Frequency range | Needed span, for example audio through 100 kHz | Span the built kit is specified to reach |
| Supply | 9 V battery, 12 V bench, or both | Current draw and included regulator |
| Output | Amplitude into the student load | Impedance and whether a BNC is fitted |
| Kit contents | PCB, case, knobs, leads | Included, optional, or absent |
The XR2206 function-generator IC is widely documented with a frequency span from 0.01 Hz to more than 1 MHz. A kit that uses that IC still needs the builder supply, waveform symmetry, and output amplitude written on the quote. A 1 MHz discussion on the IC datasheet is not a certificate that a particular board reaches 1 MHz after assembly.
Background: a classroom needs sine, triangle, and square for filter labs below 100 kHz. Process: the brief marks a function generator xr2206 kit as acceptable and marks a 60 MHz calibrated source as out of class. Result: quotes list kit contents and a supply of 9 V or 12 V, and they do not carry a calibration certificate line.
Background: a depot injects a tone into an audio path and does not need ppm frequency accuracy. Process: the buyer asks for output impedance, a rough amplitude such as 1 Vpp, and whether distortion is stated. Result: the supplier either prints a THD note or marks distortion as unstated. Measurement accuracy is not invented to fill the gap.
A function generator calibration task, a 10 MHz reference, or a four-output phase plan does not belong on a kit line. Move that work to the calibration overview or the 4 channel function generator checklist. Mixing the prices hides the missing certificate and the missing shared clock.
Sine symmetry and triangle linearity are adjustment points on many XR2206 boards. Ask whether the quote includes the trimmers and a procedure, or whether the buyer must align the board. Duty cycle range, often discussed from about 1 percent to 99 percent on the IC family or a narrower window on a given board, must be taken from the kit sheet.
Connector choice changes use. A bare pad is not a BNC. Connector mating cycle is minor on a classroom kit and material on a depot that patches daily. Ingress protection is usually absent on an open PCB. Say so, rather than copying an outdoor-radio rating. Runtime applies when the kit is battery powered. A 9 V clip without a stated current is an open question.
New kit stock versus a used board is a condition dispute. A new bag can include all passives. A used board can miss the timing capacitor that sets the frequency range. Compatible substitute ICs need the marking written on the quote. This desk does not call a substitute an XR2206 because the silkscreen says function generator.
Standards context stays narrow. IEEE 802 does not define this kit. 47 CFR Part 2 may matter if a finished product radiates, and that question is for the exact assembly, not for the IC name. ISO 9001, if a seller offers it, is a quality-system file. It does not set output amplitude. FCC and NRTL marks are requested when the finished item is claimed to carry them.
Commercial lines to separate: quantity of kits, currency, per-unit or whole-order budget, US destination, requested timing, and whether assembly labor is included. A high-end preference on this page usually means a cased kit with a BNC. A budget preference usually means a bare PCB. Undecided means the supplier should show both. None of those words is a factory rating.
Many classroom kits expect a high-impedance load. A 50 ohm scope input can collapse the amplitude. Ask the supplier for the intended load and for the amplitude at that load. Do not assume the 50 ohm bench-generator convention applies.
A short loan still needs a known frequency and amplitude if the reading will be recorded. If the kit has no calibration traceability, record the limitation in the acceptance note. A later bench generator quote should not be averaged with the kit price.
Schematic, parts list, supply voltage, and waveform list are the usual set. A missing schematic is an exclusion. Site constraints such as a shared student bench, a 120 V outlet for an external supply, or a ban on loose lithium cells belong in the brief.
There is no file upload on this form. Paste the kit bill, quantity, destination, and timing into the requirement text. The panel is a stacked note above the form, distinct from the channel-quote strip.
