Migrating From The 4284A - Keysight 4284A Technical Overview

Figure 16. Front rubber guide and STOPPER
Migration Reference
1. Maximum test signal current is 100 mA for the E4980A
and 200 mA for the 4284A
In order to perform a SHORT correction or low impedance measurement
(less than 100 ohm), the test signal voltage of E4980A must be set up so
that the total test signal current does not exceed 100 mA.
2. Selection for handler interface connection
Current Option 4284A-202 users and customers using the following compo-
nent handlers should refer to "Appendix 12" on page 26 of this document.
Some modification is necessary.
– Palomar Model M16 Handler
– Palomar Model M11 Handler
– Q-Corporation RTR2 Handler
– Isumeca 83 Handler
– EA Model M015 Handler
3. Interference of front rubber guide
The rubber guide on the front of the E4980A may interfere with some fixture
connections. Follow one of the two methods below to resolve this issue.
– Take the rubber guide off the E4980A
– Take the "STOPPER" off of the Keysight ixtures
