Agilent 8753ES System Verification and Performance Tests
Procedure
Initial Calculations
1. Fill in the attenuator error values (referenced to 0 dB attenuation) by referring to the
calibration data for the 8496A step-attenuator. Refer to the note below if the calibration
data are not expressed as attenuation errors.
a. Find the column in the 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 Table 2-1 for column B. This value should be placed in the
row for the 10 dB 8496A setting.
c. Continue transferring the remaining values of the 8496A attenuation errors to
column B in Table 2-1.
2. In Table 2-1, transfer the 10 dB error value located within the parenthesis in column B
to each space in column C.
NOTE The 8496A used for this test will have known attenuator errors for
attenuations up to 100 dB using a test frequency of 30 MHz. The attenuation
used as a reference is 0 dB. If the available calibration data are not expressed
as attenuation errors, they can be converted to such a form by the following
equation:
(actual attenuation) − (expected attenuation) = attenuator error
Actual attenuation values that are greater than the expected attenuation
values will result in positive errors. Actual attenuation values that are less
than the expected attenuation values will result in negative errors.
