Laser Soldering: minimum hole applicable and depth? :arrow:
I need to ensure that the press fit pins are very stable by applying solder to it and the best method I can think of is laser soldering after SMT + Press-fitting the connector. Unfortunately the hole diameter is 0.3mm and...
Hi forumers, I have an upconverter module rated 60W with gain of ~40dBm. I am currently connecting the 30dB 150W attenuator directly to the output port (N-type). I am planning to put the attenuator inside a testbox, so I will be using a test cable to connect the DUT. Is it safe to do so? Thanks...
How to make accurate channel power measurement (in my case using 8563E). I am seeing differences when using power meter. Using spectrum analyzer, the difference is also significant when CW is on and off from source (around 2dBm). Thanks guys.
Hi, anybody can advise an MER capable sig gen, in IF levels only; and is it possible to have it as simple and cheap as possible? (like a single pwa 2-tone siggen, but this time, MER capable). Thanks! :-|
I am more of a test guy and handling engineering questions from a PCB vendor is something new to me. Can anyone direct to a general guide about PCB manufacturing standards or checklist or a book to start from?
Hi guys and gals,
Any suggestion on a simple data acq, say 8-port, to receive 0V - 5V from a manual switch, that can also interface with RS232 or USB? Is it possible to make without using mcu?
noob question: I tested a diode fwd bias circuit measuring 12mA. When I applied negative voltage, I am expecting a very small I reading. The source meter can be set to negative voltage. Why am I seeing a negative current value? If I tried to swap polarity of voltage (and sourcemeter set to +V)...
