Electronic Counters
Direct and Prescaled


go right to the catalog! Skip the INTRO, Go RIGHT to the CATALOG!

These are the stock electronic counters we have, both direct counting and heterodyned/prescaled microwave types. These will also appear under the manufacturer on other pages for ease of searching. Every counter has been inspected, repaired where needed, cleaned and calibrated. In addition, all ovenized counters are drift tested for at least 48 hours to check long term stability, and to insure the best possible accuracy.

* NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!

You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan CLICKHERE.

Shipping*SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating.

* E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.

*There is a packing charge for large or heavy equipment, see the elsewhere in the FAQ for details.

*If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.

*If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 or FAX +1 (250) 769-4106 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.

We accept VISA/MC or international money order

* CONDITION: To answer your questions, YES, we completely check and inspect all used equipment, and do not offer any we feel is substandard. That gear is normally scrapped, broken down for parts, or may get offered as-is in the HOT DEALS section, with the unit's condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we burn in the equipment for 24 hrs. again and re-check to be sure it is good prior to shipment.

* The CATALOG will appear below shortly!
Don't forget these illustrated sections take a few seconds to load, but they are worth the wait!

VERY FLEXIBLE!
Universal Counter/Timer

High performance 125Mhz (Ch. A/B) multi-mode counter (typical performance to 135Mhz or better), PLUS optional 500Mhz C channel input (typical performance to 600Mhz). 8 Digit LED display, A/B channel inputs for timing, frequency, and period measurements, C channel for frequency only. Selectable timing resolution for versatile time/frequency/count measurements, plus AUTO mode for set and forget ability. Excellent operational and physical condition, Looks great. Carefully calibrated against our GPS slaved standard and atomic clock. Includes optional -132 ovenized timebase with 5x 10-8 stability. Requires an initial 30-60 minute warm-up/stabilization period, the calibration is based on this warm up for best accuracy. Has rear external timebase connections and monitor for use of a common high performance shop standard, or to use the internal ovenized standard. Supplemental ON/OFF switch at rear to allow full power off (otherwise ovenized timebase always runs). Has fold-out tilt bail underneath, top carry handle, plus stacking grips, a very nice high performance, compact counter.

Universal Frequency Counter

High performance 100Mhz (Ch. A) multi-mode counter (typical performance to 125Mhz or better). 7 Digit LED display, A/B channel inputs for timing, frequency, and period measurements. Selectable timing resolution for versatile time/frequency/count measurements. 2.5Mhz performance on channel B. Great for lab use, fully cal'd, overhauled and ready to go. We have both RED and AMBER display units, advise if you have a preference. Excellent operational and physical condition, Look great. Carefully calibrated against our GPS slaved standard and atomic clock. Note, these have a conventional timebase, spec is 1x10-5 over 0-50C, virtually all units can do much better, but need a 30 minute warm-up/stabilization period, the calibration is based on this warm up and a +23C ambient for best accuracy.

Sometimes we also have units with large case ID labels that can't be removed or other minor cosmetic issues, available for a $50 discount when in stock.

HP 5328A


Universal Modular Frequency Counter

High performance 100/525Mhz multi-mode three channel counter with optional very high stability 10811-60111 TCXO. 9 Digit (option 030, 8 standard) LED display, A/B/C channel inputs for timing, ratio, frequency, and period measurements. This is HP's most famous counter, widely used in industry and military service as a high performance workhorse. Selectable timing resolution for versatile measurements, fuse protected 50 ohm C channel (Optional). Great for lab use, fully cal'd, overhauled and ready to go. Has front tilt-bail feet and full width carry handle, or can be equipped for rack mounting as preferred. Very good condition. Carefully calibrated against our atomic clock, as shown in the 10Mhz display. The small error in the 520Mhz display is multiplier error in our Marconi generator, not the counter. The high precision timebase can be used externally, and all versions can accept your own shop 10Mhz standard (if available), for improved accuracy. We can provide the 011 optional GPIB interface, tested in talk mode. We can also provide many other HP options, including digital voltmeter display (of trigger threshold), no C channel input, rack mounting and handle kits, and more. E-MAIL walter for a specific configuration and quote.
