CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

I have an 8558B which becomes totally unstable if the centre frequency is set above about 1250MHz at any span setting. If the span is sufficiently wide it is clear that the SA it is covering perfectly

Re: HP436A LED Display Driver IC - HP1820-1361 - 9374DC - Where to get?
According to the 436 manual, 1820-1361 is a Fairchild 9374DC. From the schematic it looks like some BCD to 7 segment decoder. Quite a different beast then the 75491 which seems to be just 4 drivers.
