HP 8530A F eatures
Measure P arameter 1, 2, 3 or 4 in Any Combination
Y ou can measure from 1 to 4 ratioed or non-ratioed parameters on any given trigger (HP-IB or
External).
Save/Recall Registers
The receiver has eight Save/Recall registers . Each can save current measurement settings for
instant recall at a later time . Register-8 is the \User Preset" register . Settings saved under
register-8 become active whenever you turn the receiver ON, or when you press 4
USER PRESET
5 .
Measure P erformance Relative to the P eak of the Main Lobe
The Normalize Trace function sets the peak of the main lobe (the data point of highest
amplitude) to 0 dB . Y ou can then use markers to view trace magnitude values relative to this
reference point. When data is saved, printed, plotted, or transferred to a computer , magnitude
values will be relative to the peak. This feature is under the RESPONSE 4 MENU 5 key .
Remote Programming
The HP 8530A can be controlled remotely from any computer that can communicate using
HP-IB . All front panel features are supported, plus many functions which are only available
via HP-IB . Y ou can query the analyzer to determine current modes of operation and current
instrument or system status .
Data Presentation F eatures
The HP 8530A can show measurement results on its display . It can display:
Antenna patterns
Frequency response measurements
Time domain
Radar Cross Section (RCS) frequency and time domain measurements
Return Loss or SWR
The HP 8530A allows you to print or plot measurement results .
Display F ormats
Y ou can select logarithmic or linear magnitude display formats (Cartesian or polar), or
phase display format (Cartesian only). Y ou can display one , two , three , or four parameters
simultaneously on the screen.
Multiple Measurements Can be Shown Simultaneously
The HP 8530A allows you to view up to four parameters at once , in split or overlay
presentation. Alternatively , you can display one parameter from each of the independent
measurement channels (more on channels is explained later).
Trace Memory and Trace Math
The trace memory feature is similar to the storage feature in a storage oscilloscope . Y ou can
store the current data trace to memory , then compare it to subsequent measurement traces .
Trace math features allow you to perform vector addition, subtraction, multiplication, and
division. These operations are performed using the current data trace and the memory trace .
Each parameter has independent trace memory/math operation. In addition, trace math in
Channel 1 is independent from trace math in Channel 2.
