Glossary
Hardware State
The Hardware State stores multiple source mode settings , HP-IB settings for external
hardware , and frequency converter or test set states . The hardware state can be stored to
disc . This feature allows you to quickly recongure the receiver for dierent test setups .
Hold Mode
Hold Mode stops measurements . Y ou should place the receiver in this mode if you want to
load measurement data from disc . The receiver selects Hold mode after measuring a single
sweep , single angle , or number of groups .
Input
Refers to the four HP 8530A signal inputs (a1, a2, b1, and b2). This word is also used when
referring to the signal inputs of the frequency downconverter .
Instrument State
An \instrument state" is dened as the condition of all current measurement settings ,
including all domain, stimulus , parameter , format, and response settings .
LIF
Logical Interchange F ormat, the disc format used by HP 9000 Series 200/300 computers .
Machine Dump
A Machine Dump stores the following register contents to a single disc le:
Current instrument state
Instrument states 1 - 8
Cal sets 1 - 8
Cal kits
Hardware state
Memories 1 - 8
Machine dump les allow you to change between dierent test congurations quickly .
This feature is useful if you have an HP 8530A with optional HP 8510C operation. Here's
why: When you change between HP 8530A and HP 8510C operation, the receiver reverts
to factory-default settings , and the contents of all registers is lost. A machine dump can
store all these settings to a single disc le , so you can reload the machine dump and restore
your setups immediately . NOTE: Before saving a machine dump le , make sure you save
the current settings to Save Register 8 (the user preset register). When you later load the
machine dump le , the machine will wakes up in the desired state .
Measurement
A \measurement" is a completed data collection activity . What constitutes a measurement
depends on the mode you are in.
Measurement Denition when Using R amp Sweep Mode
In Ramp sweep mode , a \measurement" is a complete sweep spanning the start and stop
frequencies . One sweep must be measured if averaging is OFF . If averaging is ON, n + 1
sweeps must be measured, where n is the selected averaging factor .
F or example , assume you select four parameters , ramp mode , and averaging is set to 4. T o
take a fully averaged measurement:
If using Continual mode , allow ve sweeps to complete . After ve sweeps the data is
fully averaged.
If controlling the receiver by computer , set Number of Groups (NUMG ) to 5.
