Check your high speed oscillator circuit for the source of the "chirping". If the oscillator circuitry is not working properly, the CRT cannot display a picture on the screen. SAMS schematics is a good source for wiring diagrams, schematics, and instruction manuals. Good luck!

I am trying to repair the switching power supply of my Advantest R4131A spectrum analyzer. It has the number PTA465-00 and was made by Fuji Electrochemical (www.FDK.co.jp) about 20 years ago. I found a similar schematic on www.coilws.com in "A sample Switch Mode Power Circuit" page.The difference to...

Hi all: Don't know why my initial registration got lost in space, but since I am here it must have arrived. Was going to reply to an electronics question (RC oscillator), but no pictures (formulae, schematics, etc.) are visible. I use IE9 and Outlook Express. Any help? Thanks...

What I want to do is test an oscillator of an RTC. How do I connect it to an oscilloscope.. do I need a timer? I have a DS1307 in had.. For now, I want to know the schematic to connect it to a scope.. Regards, M.T...

hiii all, to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase...

SiTime Corporation has shipped 100 million units of its MEMS devices, including oscillators, clock generators and resonators.

Ecliptek?s EMRE series of four surface-mount LVDS MEMS oscillators enable output frequency up to 625MHz with a frequency stability of ?20ppm.

IQD has launched a newly designed high-temperature clock oscillator. The new LHAT series is housed in a 7x5mm dual hermetically sealed ceramic package with gold plated kovar leads attached using a robust eutectic brazing process. The oscillators are capable of operating at temperatures from +25 to +200 degrees C. The LHAT series is available with a frequency range of 320kHz to 50MHz, a frequency stability of ±100ppm over +25 to +150 degrees C, and also ±175ppm over +25 to +200 degrees C for applications which need a higher temperature range. Operating at 3.3V this CMOS output clock oscillator can withstand a shock of 30,000g, 0.3ms. ½ sine and a vibration of 20g, 10-2,000Hz swept sine as per MIL-STD-202G Method 204D condition D. The unique method used to connect the leads to the package reduces the mechanical and thermal mounting stresses, making the LHAT series ideal for applications which are used in demanding mechanical and high thermal situations including: downhole instrumentation, rotary shaft sensors, underground mining tools and avionics applications.
