E8362/3/4C Option H85
Description
Description 
The Agilent E8362/3/4C Option H85 is a modified version of the standard E8362/3/4C PNA 
Series Network Analyzer. Option H85 is designed to permit insertion of high power 
amplifiers and other signal conditioning equipment to allow high power network 
measurements at RF levels up to 20 Watts (+43 dBm) from 10 MHz to 40 GHz and 10 
Watts (+40 dBm) from 40 GHz to 50 GHz. Refer to Figure 3, Figure 4 and Figure 5 for high 
power configurations. 
The Option H85 does not increase the output power of the E8362/3/4C analyzer. This 
option only allows the E8362/3/4C analyzer to make high power measurements. The user 
must supply there own amplifier(s) and external components such as high power, couplers, 
attenuators and isolators to configure the analyzer for high power. These components are 
not supplied, or included with the Option H85. The user is responsible to ensure that these 
components meet their DUT requirements, and also protect the PNA from damage. 
Therefore, it is very important that you read this document thoroughly and follow the 
power level specification or guidelines in Table 1 through Table 7.
E8362/3/4C Option H85 combines and bundles Option *UNL, 014, 016, 080 and 081. 
The difference between Option H85 and the combination of the options listed above is that 
Option H85 deletes the bias tee’s from the *UNL option. Option UNL, when configured 
with Option H85 only includes the two source attenuators.
