I've lowered the gen frequency on its big brother the N1996A and it works fine but I don't have an E7495A to experiment with. |

That's great! Can you say how you did that? Richard AE6XO |

Regarding "I've lowered the gen frequency on its big brother the N1996A and it works fine but I don't have an E7495A to experiment with." Could you describe what "it works fine" means? have you done 2-port or 1-port measurements at a lower frequency range (let's say 1MHz or 10MHz) and have you compared the measurement with other VNA? Do you remember what exact file and parameter you have changed? |

I lowered it to 1 MHz and it still normalized fine. Its performance was just fine for return loss measurements of HF antennas. |

There is a model description file in the N1996A firmware that lists the frequency range of the freq generator. If you change the starting freq from 10 to 1 MHz it will obey. |
