Recording equipment and oscilloscopes, as follows 1. Digital data recorders having all of the following: a. A sustained ‘continuous throughput’ of more than 6,4 Gbit/s to disk or solid-state drive memory; and b. A processor that performs analysis of radio frequency signal data while it is being recorded; Technical notes: 1. For recorders with a parallel bus architecture, the ‘continuous throughput’ rate is the highest word rate multiplied by the number of bits in a word. 2. ‘Continuous throughput’ is the fastest data rate the instrument can record to disk or solid-state drive memory without the loss of any information while sustaining the input digital data rate or digitizer conversion rate. 2. Real-time oscilloscopes having a vertical root-mean-square (rms) noise voltage of less than 2 % of full-scale at the vertical scale setting that provides the lowest noise value for any input 3 dB bandwidth of 60 GHz or greater per channel;
