Interestingly, three defective SRAMs on three instruments. Maybe a lot born bad? If you can be interested in the attachment there is the B18 firmware. |

It's a shame the unit in the pictures here was used in a dust factory! |

I'm trying to repair a faulty 2306 battery simulator. Q421 current regulator is faulty. Can anyone help with identifying the part number for Q421, Keithley Part number is TG341. It could be the 1N5297UR (1mA constant current regulator) or the 1N5298UR (1.1mA). |
