General Information RF Network Analyzers
1-78 Service Guide
1. Measurements are always made with error correction enabled.
2. Center frequency is set to 1 GHz.
3. “Cycle Time” is the time required for the analyzer to finish one complete
sweep cycle including the forward sweep, retrace, bandcrossings, and calcula-
tion time when in the “Continuous Sweep” mode.
4. This is the time to recall both the system state and calibration data.
5. “Data Transfer” is performed using an HP S700 workstation. The GPIB port is
used to transfer “corrected” 64-bit, floating point numbers (real and imagi-
nary).
6. A “Measurement Cycle” is defined as the time required for an HP S700 work-
station to control the analyzer to: (1) recall the state and calibration (analyzer
is now in “sweep hold” mode), (2) sweep (using the “:INIT1;*OPC?” command),
and (3) transfer data. This may be less than the sum of the other columns
since a complete “Cycle Time” doesn’t need to be done for the controller to
transfer data.
