?I have a Schlumberger 4002 signal generator, I need help with a pin diode in this unit.
The pin diode is QPND 4709?(HP manuafacture), I can't find it anywhere, I am looking for this or a replacement for it, would like a non smd, since layout is for leaded axial type. I have no experience with pin diodes and need help. The pin diodes is used for AM modulation and level adjustment of the carrier, please see the schematic I attached.?
Thank you.
