Hi All -- You all have a lot of experience with equipment. I just picked
up a Fluke 6061A and I'm happy to say it mostly works. But... at
frequencies below 250 MHz, as the frequency output is decreased, the
level drops too, and starting from +12dBm (rated out, more-or-less), by
20MHz, the positive peak of the sine wave is flattening -- this
progression of level drop and increasing distortion keeps on until the
bottom at 10kHz, where the level is over 4dB low and distortion is
I'm a complete novice to this instrument and to synthesizers in general.
I can use some tips about what circuits or parts might be causing this,
or where to look to start on a fix. I do have a manual with schematics.
I seem to recal reading that there is a Low Band circuit that works at
245MHz and below, so it seems like that may be where to start looking.
Any and all suggestions appreciated.
I welcome off-list comments if that seems most appropriate.
And, sorry, if you're also a time-nut, you got this twice.
