Ramsey CT-90 - Portable Frequency Counter

Here is a vintage frequency counter that you can build and use it for learning and experiments in your home or office lab. The front end circuits have to be studied. This will help young enthusiasts learn some basics of instrumentation. - delabs Notes

Ramsey CT-90 - Portable Frequency Counter 

The CT-90 is a laboratory quality frequency counter that is capable of use in the lab as well as in the field. Utmost care has been taken in all the design stages to insure that sensitivity and reliabilty were not compromised. The CT-90 has been specifically built for the critical user, as demonstrated by; special  timebase options, nine digit display, three gate times, and a count hold feature.

Ramsey CT-90 - Portable Frequency Counter Schematic


The CT-90 is ideal for portable usage. Leading zero blanking and the micro power oven (optional) allows 2-4 hours of continuous operation using the internal battery supply.

Operation; Operation of the CT-90 is very simple, simply connect your input signal to the proper input jack (10, 60 mhz or 600 mhz) and select the range and gate time. All switches, except the external time base switch (optional) are mounted on the front panel in easy view of the user. A description of the front panel controls follows.

PICMG - Open specifications for Modular Computing

PICMG is a consortium of companies who collaboratively develop open specifications for high performance telecommunications and industrial computing applications.

PICMG - Open specifications for Modular Computing

Founded in 1994, PICMG’s original mission was to extend the PCI standard to non-desktop applications. The formal name of the organization is the PCI Industrial Computer Manufacturers Group. It is now known as PICMG (pronounced “PICK-EM-GEE” or “PICK-MIG”).

Specs and Standards for Advanced Mezzanine Card, AdvancedTCA, COM Express, CompactPCI, e-PCI-X, MicroTCA and others.

PICMG - Open specifications for Modular Computing

PICMG 3.7 AdvancedTCA

To better address the datacenter market PICMIG has developed thePICMG 3.7 AdvancedTCA specification, as an extension to the existing ATCA standard. The extension utilizes the available depth in server cabinets and the environmental characteristics of datacenters to dramatically increase the power and throughput, while reducing the cost of the systems.

PCI-ISA - Passive Backplanes - "The PCI-ISA passive backplane standard moves all of the components normally located on the motherboard to a single plug-in card. Looking much like a standard ISA or PCI card, a PCI-ISA CPU card has two edge connectors on it - one for the PCI bus and one for the ISA bus. The "motherboard" is replaced with a simple "passive backplane" that has only connectors soldered to it."
