Performing The Tracking-Generator Self-Calibration Routine - HP 8590 E-Series User Manual

001 (7562 input), use the 750 calibration cable shipped with the analyzer. Use only 750
connectors to avoid damage to the RF input connector.
Note
Option 105 only: Remove all connections to the GATE TRIGGER INPUT
rear-panel connector before performing the self-calibration routines.
6. Perform the frequency and amplitude self-calibration routine by pressing (CAL) and
CAL FREQ & AMPTD . During the frequency routine, CAL: SWEEP, CAL: FREQ, and CAL: SPAN
are displayed as the sequence progresses. For an Option 102, CAL: FM GAIN + OFFSET is also
displayed.
During the amplitude routine, CAL; AMPTD, CAL: 3 dB BW, CAL: ATTEN, and CAL: LOGAMP are
displayed as the sequence progresses. CAL: DONE appears when the routine is completed.
Any failures or discrepancies produce a message on the screen; see Chapter 9.
7. When the frequency and amplitude self-calibration routines have been completed
successfully, store the correction factors by pressing CAL STORE.
The self-calibration routines calibrate the spectrum analyzer by generating correction factors.
The softkey CAL STORE stores the correction factors in the area of spectrum analyzer
memory that is saved when the spectrum analyzer is turned off; the spectrum analyzer will
automatically apply these factors in future measurements. If CAL STORE is not pressed, the
correction factors remain in effect until the spectrum analyzer is turned off.

Performing the Tracking-Generator Self-Calibration Routine

For spectrum analyzers with Option 010 or 011, the tracking-generator self-calibration routine
should be performed prior to using the tracking generator.
Note
Since the tracking generator calibration routine depends on the accuracy of
the absolute amplitude level of the spectrum analyzer, the spectrum analyzer
amplitude calibration should be done prior to using CAL TRK GEM .
1. To calibrate the tracking generator, connect the tracking generator output (RF OUT 5OR) to
the spectrum analyzer INPUT 500 connector, using an appropriate cable and BNC-to-Type
N adapters. If the spectrum analyzer has Option 001 (750 input), use the 75Q calibration
cable shipped with the analyzer. Use only 75fl connectors to avoid damage to the RF input
connector.
Note
A low-loss cable should be used for accurate calibration. Use the 509 cable
shipped with the spectrum analyzer. If the analyzer has Option 001 (75n input),
use the 75R cable shipped with the spectrum analyzer.
2. Press the following spectrum analyzer keys: m), More 1 of 4 , More 2 of 4 , then
CAL TRK GEN . TG SIGNAL NOT FOUND will be displayed if the tracking generator output is
not connected to the spectrum analyzer input.
3. To save this data in the area of spectrum analyzer memory that is saved when the spectrum
analyzer is turned off, press CAL STORE .
