HP 8753E - Initial Calcuiations

Initial Calculations
1. Fill in the attenuator error values (referenced to 0 dB attenuation)
in Table 2-l by referring to the calibration data for the HP 8496A
step-attenuator. Refer to the note on the previous page.
a.
Find the column in the HP 8496A attenuation error table that pertains to
the attenuation errors for 30 MHz.
b. Starting with the “10
dB” step in this column, write down the value in
the corresponding space in ‘Ikble 2-l for column “B.” This value should
be placed in the row for the 10 dB HP 8496A setting.
c. Continue transferring the remaining values of the HP 8496A attenuation
errors to column “B” in lhble 2-l.
2. In ‘lhble 2-1, transfer the 10 dB error value located within the parenthesis in
column “B” to each space in column “C.”

3. The values in column “D” result from changing the reference attenuation of
the calibration data of the HP
8496A to 10 dl3.
