1: Option 001 (optional time base) is not required, when a frequency standard in T
able 1-2 is available.
2: Required for testing an analyzer equipped with Option 1D5 (High Stability Frequency Reference).
3: Calibration values at 50 MHz are required in the tests
. See the Calibration Data Required for Step Attenuators
later in this chapter.
4: An HP 8496G step attenuator with required low VSWR (
 1.02) can be purchased by specifying option H60.
5: Required when an HP 8496G step attenuator is used in the tests
.
6: The HP 85032B includes a type-N(m) 50  termination.
7: An HP 8491A Opt. 006 xed attenuator with required low VSWR (  1.015) can be purchased by specifying Opt.

9: The HP 11851B includes three N(m)-N(m) cables of 61 cm and a N(m)-N(m) cable of 88 cm.
10: The HP 85032B includes two APC7.5-N(f) adapters.
Calibration Data Required for Step Attenuator
The four performance tests listed below measure the analyzer's performance against a known
standard (the attenuation values at a frequency 50 MHz of the HP 8496G Opt. 001 and H60
step attenuators).
