Table 9-5 System Performance, Uncorrected, 50Ω
a. Option 1E1 adds a 60 dB step attenuator to the HP 8712ET/8714ET.
b. These numbers apply for a measurement made using the “Fine” bandwidth at an environmental tempera-
ture of 25°±5° C.
c. The uncorrected directivity of a network analyzer is calculated in linear terms by dividing the reflection
measurement of an ideal load by the average of the reflection measurements of an ideal short and an ideal
open.
d. The uncorrected source match is the source match of the network analyzer when making a ratioed, uncali-
brated measurement.
e. The uncorrected load match is the match of the network analyzer port used on the load side of a measure-
ment.
f. Measured by setting output power to the maximum specified setting, connecting shorts to both ports, and
measuring transmission. Typical and specified crosstalk values are 5 dB worse than those shown in the
table below 1 MHz (for all models) and above 2.2 GHz (for 8714ET/ES models).
