For the record, It is more or less flat response up to 400 MHz, and good to above 1 GHz.
The Racal equivalent uses a diode bridge on the input, but on the meter scale that READS 6dB higher than the Marconi TF2603.
This is rather pedantic in form, I am just trying to see some standard, if possible.
I need another TF2603 user to let me know if the Marconi should be reading the same or not really, or circuit design measurement notes could be confusing having two standards as it were... I guess it leads to notes on notes lol
