ERR 360 SPAC CAL The start bucket correction is out of range.
ERR 361 SPAC CAL The percent of span correction is out of range.
Error codes 400 through 599 relate to IF failures. Instrument
service is required These errors are generated when the automatic
IF adjustment routine detects a fault. These errors are designed to
assist service personnel in IF problem isolation, however, an
instrument will function if the suspect functional parameters are not
required. This routine adjusts amplitude parameters first, then
resolution bandwidths in this sequence: 300 kHz, 1 MHz, 2 MHz, 100
kHz, 30 kHz, 10 kHz, 3 kHz, 1 kHz, 300 Hz, 100 Hz, 30 Hz, 10 Hz, 3 Hz,
and 1 Hz. The routine restarts from the beginning if a fault is detected.
Resolution bandwidth filters adjusted after the routine begins and
before the fault is detected should be acceptable; resolution bandwidth
filters adjusted later in the sequence are suspect. If the fault is detected
before the first resolution bandwidth (300 kHz) is adjusted, all IF
performance is suspect.
