TinySA4

FRANCISCO JAVIER MURIEDAS ARGUMOSA All Messages By This Member #4344 A day or two ago I thought I read a message from Erik here in which he referred to a measurement up to more than 4GHz with a TinySA4? and I was excited that I was creating a new 4 "TinySA with a much wider frequency margin. I thought to comment but had to leave. I looked for that message later and I can't find it. I dreamed it, lost it or was it withdrawn? Someone saw it plus? Thanks - EA1AWY Javier Muriedas (Gijón, Asturias, Espa?a)

Ton - PA0ARR All Messages By This Member #4355 you can measure higher frequencies , using an external mixer connected to the TinySA. Erik adapted only the firmware so you could see the right frequency in the display. see msg #4229 73 - Ton PA0ARR

From 140MHz? to 2.14GHz From 2.35GHz to 4.35GHz Note the 2 GHz SPAN. Our tinySA?s max. SPAN is 720 MHz. in HIGH , (even shifting the frequency, the maximum available SPAN remains at 720MHz.) Is tinysa4 the new tinsa that Erik is investigating? or... Is there some way of compressed sampling thus increasing the span? or is it an Erik joke?
FRANCISCO JAVIER MURIEDAS ARGUMOSA All Messages By This Member #4369 Initially I thought the same as PA0ARR, but frequency translation with a mixer does not extend the span as aciscar indicates. Even if we used a harmonic of the square wave oscillator of the TinySA (for example 700MHz to obtain an offset of 2100MHz) the achievable span could not exceed the maximum of the TinySA (which would triple the frequency jumps). Also, the ending "4" seems to excite our minds eager for bigger screens and margins. Will it be a "probe balloon" to put on our long teeth? In any case, another genius of this instrument and this forum. Congratulations!! - EA1AWY Javier Muriedas (Gijón, Asturias, Espa?a)
