-* These figures take into account the effects of a 100 MHz oscilloscope. There appears to be little or no electrical difference between the early and late families of the Tektronix current probes.
-Note that in every case, the passive termination is better for high frequency response, while the Type 134 improves the low frequency response.
+(*These figures are system numbers and take into account the effects of a 100 MHz oscilloscope. There appears to be little or no electrical difference between the early and late families of the Tektronix current probes. P6019 & P6020 figures are from from the 1968 Tektronix catalog and do not include the oscilloscope. it's hard to understand some of them given the stated 54 MHz bandwidth of the Type 134.)
+Note that in every case, the passive termination is slightly better for high frequency response, while the Type 134 improves the low frequency response.
