¿ªÔÆÌåÓýn8zmTWH@... : I do not have/searched the schematics of my particular ATT. I based my assumptions on a previous post from someone that attached schematics. They may not be the right ones. ? My exact model number is : 33321-60036 it goes to 70dB I think. My 8594E is from 9kHz to 2.9GHz. Measuring the pads where the contact blades touch when selected, still in the aluminum block I get these readings : They are in order from Input to Output. ? PAD 2 : 81.69 ohm PAD 3 : 98.04 ohm PAD 4 : 51.65 ohm ? ? ? From: [email protected] <[email protected]>

Using the p-p amplitudes shown in the lower left corner of the screen, I calculate 20 dB where you said 40, and 30 dB where you said 50. Are you sure that is a 40 dB section, as that is kind of uncommon in the HP attenuators I¡¯ve seen? They would usually get 40 by turning on two 20¡¯s. Getting 40 dB across one section is asking a lot of the isolation across that section as the frequency goes higher. ? From:

On Behalf Of Nicolas Mailloux ? I enabled FFT on my DSO. (It is a Rigol D1052E hacked to 100Mhz) My TF 2015 is old and the maximum dB out I can get is theoretically -1dB (-7dB on the dials and a +6dB boost on CW Mode) ? First picture shows without any attenuation Second shows the 40dB attenuation Third shows 40dB + 10dB attenuation. ? I will clean contacts and re-measure later. ? ? From:
