×
  • The model 1823A is a reciprocal 2.4GHz universal frequency counter that is microprocessor controlled.
  • The LED display can provide nine digits of resolution using the internal 10s gate time.
 
A self-­test mode is also provided for a quick check of several facets of operation. Each operating mode can be selected by front panel push button switches with automatic decimal points and indicators. The high accuracy, sensitivity and versatility of this counter make it an extremely valuable instrument to scientists, engineers, experimenters and communications technicians.

First when I made the order I was pleased with the shipping, very fast the item arrived on time. The item was packed very well, The controls functioned very well, the operation of the controls was fine, testing was carried out with the actual displayed testing was excellent. A best buy. I would recomend this test equipment.

Works great for our needs.

This unit can get up to 9 digits of resolution for very accurate readings. We only use it up to 7 or 8 digits of resolution for fine tuning two way HF radio equipment. We make use of the Low Pass filter while measuring low frequency crystal oscillator signals down to 10Mhz.One thing I would have liked to see though is a better quality BNC cable and a quality set of test leads. Even with that being said, a great value for the price.

Ok for the price, but...

Users should be aware that the "RS-232C" interface on this unit is not standard RS-232. The 1823A does not have its own /-12v supply for the serial port. You have to supply an external 12v on the DTR pin and an external -12v on the RTS pin. BK supplies a Windows program to that should setup a PC's serial port this way, but I could not make this program run on Windows7. I had to write my own program that forced the RTS/DTR pins of a USB serial adapter to the right state before I send or receive any data from the 1823A.

Overall Good Value - Entry Level

If you're looking for a good entry level frequency counter then this unit might just fit the bill. It not a high performance unit and it doesn't have a high performance price.
