While i was working with my own GPSDO project. i need to have a frequency counter with descent stability so purchased my self a Agilent 53132A which is a 12 digit frequency counter , big brother to 53131A 10 Digit Counter. Both are really nice units.
But they unusable standard Timebase. So optional oven oscillator time base need to purchase. but 53132A and 53131A both unit are no longer available for sale. and neither of the Time base upgrades.
At first i decided to look around for time bases on online retail sites as already knew other people are selling them.
But i had few doubts , how well the whole thing is put together. what kind of parts they have used? How good is oven they are using? and Are they using same parts as per the original Agilent time base?
As it is quite normal for stuff listed on common online retail sites, It are quite cheaply made. and i found not even a single Time base who provides exact Bill of martial and give any specification details about the OCXO they are having. ofcourse OCXO is quite expensive so they all were using old OCXO which is totally fine but some data should be available.
