Please note that while the manufacturer specifies a 100MHz bandwidth and 1GSa/s sampling rate, some user reviews suggest that the actual performance may differ, with effective bandwidth closer to 25MHz and a sampling rate of 200MSa/s. Therefore, for applications requiring precise measurements at higher frequencies, it is advisable to consider these user observations.
