Very interesting, I might have to give that a go myself. Thanks for letting us know. |

I tested with my 8656A today... The FFT is enabled The vertical 25ns and 10ns makes no difference Can't see signals beyond 30MHz So, its a half a hack, enables a near to useless FFT mode. I believe the FPGA must be updated or maybe a resistor config in board. One thing I've noticed at version 1.1.5 in both 1602B and 1604B, the measurement menus does not works properly after update. You cant select measurements, the scope works fine but the values wont "select", there is a workaround tough, to do a power cycle. I'll flash the 1602B firmware back and open a ticket with Keysight, that's a serious bug |

-3db point on mine is 25.3MHz. |

That doesn't sound too good. At least you have the old firmware to go back to. I wonder how much support Keysight will provide for this, the last firmware update was 2012, which is quite some time ago. It is quite likely that there are hardware differences between the two to give the higher bandwidth. As far as I know, there was never an upgrade option available from Keysight to take the U1602B to the U1604B, which there usually is if it is just a firmware license. |

Its someone have NAND dump for 1602 or 1604 scope? I have problem after unsuccessful firmware update. |
