The most important elements for frequency counter should be acquisition rate and count range, the former is related to the max frequency, and the latter is related to the max count range.
Other elements can be also taken into your consideration, such as accuracy, statistics, duty cycle, etc.
Here we take Suin frequency counter as examples for your reference.
| SS7200 Series | SS7300 Series | SS7400 Series | SS7406 | |

| Display resolution | 8 digits/s | 10 digits/s | 11 digits/s | 11 digits/s |
| Time resolution | 2.5ns | 500ps | 150ps | 25ps |
| Period | 5ns-1000s | |||
| Time interval range | 10ns-10000s | 1ns-10000s | ||
| Statistics | Multi-average, Max, Min, PPM, SD, Allan Variance | |||


In order to meet customers' testing requirement, Suin also developed some channel options for the universal frequency counters, from 3GHz to 40GHz which can be installed to the frequency counter to improve the frequency testing range.
If you need frequency counter or have some special requirements, please contact Suin.
