My father was a ham in the 1950s and he used a home brew voltmeter and GDO and that was it. Clearly standards have to be better than that now but do we need them to be £1000+ better? --- End quote --- Very true; see the aphorism in my .sig :) |

hello again, in my shack I have : kenwood ts-950sd and ts 780a I like if posible a list with oscilloscopes for using in hf (30mhz) {I know the difference analog/digital } A simple list s'il vous plait , not fights, peace not blood . Tkank's again all of you . |

If you're HF and RF only you're mainly interested in periodic signals so any 100MHz scope will do the job. That will allow you to see some distortion without costing too much. Rigol DS1054Z if you want a new one. Any Tektronix analogue scope that works (4x5 series, 22xx, 24xx, 26xx series) which is second hand and tested working with at least 100MHz bandwidth is good too. You don't need a lot. The digital scopes mainly come into use in non-repetitive and slow signals which there aren't a lot of in RF work. --- Quote from: tggzzz on October 25, 2017, 08:44:46 am ---Very true; see the aphorism in my .sig :) --- End quote --- Didn't see that - I agree! (well the half of me that doesn't have TEA does :) ) |

Thnk you for your interest/replay. I bought an oscilloscope Lecroy 9430.Need help about a manual I find only a remote control manual but not a user manual. Please help. Thanks. |
