Keysight 11683AZ Option H01 Operating and Service Manual
Description
The 11683AZ Option H01 is a standard 11683A range calibrator that has been modified so that it
will operate with either the Internal DC-Reference source, or an external programmable
DC-Reference source.
Specifications
External DC Reference is the same as the Internal Reference.
Operation
The 11683AZ Option H01 range calibrator allows a user to select either an internal or an external
DC-Reference source. With the
REF SELECT
switch in the
INT
position, the range calibrator is
operating manually with the Internal DC-Reference source. With the
REF SELECT
switch in the
EXT
position, the range calibrator can be programmed remotely with a programmable DC source. In
this mode of operation, the
REF SELECT
switch disconnects the internal DC source, and connects
the external DC source to the sampling gate assembly (A3).
In all other respects, the 11683AZ Option H01 operates the same as the standard 11683A.
The typical input voltages corresponding to the different range settings are:
The above calculated voltages for range 100 mW to 300
μ
W are based on the table shown in the
11683A Operating and Service Manual (11683-90014). The remaining voltages are based in the
voltage divider circuit (A1), and the input resistance (A1R1, A3A1U1R1 and A3R1), of the sampling
gate assembly shown in the 11683A Operating and Service Manual (11683-90014).
NOTE
Note that the 11683AZ Option H01 is not equivalent to the standard 11683A. When ordering this
product, you will need to order 11683AZ Option H01 instead of 11683A.
