I have been "lazy" enough to ignore the CW setting. Just used center frequency and zero span, as on other pro analyzers I have used before. Being lazy requires twice the effort. Did things so much in a hurry I sidestepped CW 73, Jose, CO2JA On 6/1/20, Rudolf Schaffer <rudolf.schaffer@...> wrote:

Thank you for your message.? I tried the "0" span solution but nanovna-saver refuse a null value for the span. 73 QRO de Rudi, HB9ARI Le 01.06.2020 ¨¤ 17:07, Jose Amador a ¨¦crit?:

Above I've used PuTTY to set the NanoVNA center frequency to 50 MHz, and the span to 0 Hz to put the NanoVNA in CW mode. 2. Once in CW Mode you can use "sweep center <frequency in Hz)" to change subsequent CW frequencies (75 and 100 MHz above). If your terminal program has scripting, then you can automate setting the CW mode and sweeping frequencies. - Herb |

Herb,
Thank you for your answer and help. Unfortunately, i can send commands but they are too many characters and PuTTY stops sending to the NanoVNA. May be, my FW version " 0.8.4.6 - 96kHz ADC, 800Hz, sweep_points 201, by DiSlord " is not compatible with serial ? I will continue to search a solution. Best regards, Rudi |

Thank you for your aswer. As i wrote to Herb, i should have problems to send commands to the NanoVNA.

When I checked the accuracy of the internal ref I just put in center freq and nothing else and it came up at what I put in, no sweeo. |
