partridges divider box?

If I get a Extron ADA 3-80 distribution amp, will it be able to run
on both the 10MHz T/Bolt output, AND on the outputs of one of David
Partridge's nice divider boxes I have. It It divides from the 10 MHz
input. There are separate outputs for 10 MHz, 5 MHz, 1 MHz, and one
that can be configured for 100 kHz / 10 kHz / 1 kHz / 100 Hz / 10
Hz / 1 Hz.
If not, is there anything available?
Thanks.

Chris, if I understand your question correctly, the answer is "Yes".
The ADA-3-80 has four separate channels (R, G, B, Sync), and
multiple outputs for each channel. So, you can input up to four
separate frequencies and get up to four outputs for each channel.
Quite a versatile little box.

I have been offered one of these:
http://www.extron.co.uk/product/product.aspx?id=ada6300mxhv
Specifically the model :
ADA 6 300MX HV HDTV RGBHV 1 x 6 Analog Video Distribution Amplifier
I *THINK* it should meet my needs except the HV bit worries me. It
seems this means it has not got unity gain, but a gain of 0.7 or 1
volt, switch selectable. Could anyone comment if it's suitable to use
my Trimble Thunderbolt with several pieces of test gear at the same
time? Thanks. Here in the UK the ADA-3-80 seems a rare find.

Hi again, Chris;
The HV at the end of the model number indicates that the unit is capable of
handling high voltage (up to 5V - TTL level) on the sync channel. The
0.7/1.0 Volt switch is to provide a bit of extra gain for long cable runs.
Aside from the HV difference, the unit appears to be very close to the ADA
3-80 in capabilities. It looks quite well suited for a DA. It has more
channels than the ADA 3-80; a big plus. The HV option is not a detriment...
the sync channel can be used for TTL level signals., whereas the normal
channels are for low-level signals (0.3 - 1.5 VPP).
Just curious, how much is this unit being offered to you for?
Cheers,
Dave M
