Description: Features: Marker Generator generates precision pulse waveforms into 50 ohm BNC connector for timebase and calibration purposes. Timebase stability is +/-50ppm. Design mixes high speed digital timebase generation with UHF saturated switching PNP output stage for high signal fidelity over coax cabling. Jumper configurable 51 ohm output impedance matching resistor. Frequencies: jumper configurable 20MHz, 10MHz, 5MHz, 2MHz, 1MHz, 500KHz, 200KHz, 100KHz, 50KHz, 20KHz, 10KHz, 5KHz, 2KHz, 1KHz, 500Hz Pulse width options: jumper configurable 10ns, 30ns, 60ns wide. Output waveform: ~600mV (no DC offset), approx. 5ns rise, 7ns fall Power: +5V, 40mA current drain with no load. PCB can be mounted to a chassis with up to four screws, or may be suspended behind the BNC connector mounted to a panel through 1/2" hole. PCB specs: 52.71mm x 40.01mm, 2 layer, FR4, 1.6mm thick, 1 oz copper, green soldermask, white silkscreen, HASL finish (not lead free) This is not a kit. Assembled prototype shown for reference only. I will supply the bare board, a schematic (with purchase), board outline, detailed assembly/calibration instructions, and a general parts list. General means not specific - the parts list might call out a LM358N, but you order #LM358N/NOPB. Or you choose a different, but equivalent part. You, the assembler, will do some minor research to create a purchase list. You will need pcb soldering/assembly skills, including minor surface mount components. You will research/source parts, and assemble/solder/test/calibrate the final product. You will need a two channel scope to evaluate signal quality. That's the extent of the support. If that's uncomfortably vague, then don't buy this pcb. No free engineering - sorry!
