1250 Frequency Response Analyzer Additional Displayed Information
AMK/1250/3 11-3
11.1.3 MAIN STATUS
Soft Key Page Display
GEN 1 GENERATOR RUN/STOP/FAULT WAVEFORM sine/square/triangle
CARRIER NONE/LO/on MODoff/1on/2on
Notes: GENERATOR FAULT indicates that the Generator board is
missing.
CARRIER NONE indicates that no Modulator/Demodulator
board is fitted.
CARRIER LO indicates that a carrier is present, but at
insufficient amplitude.
2 FREQ (Hz) AMP (V) BIAS (V)
value value value
Note: The units of frequency and voltage remain constant; exponent
notation is used to cover the full range.
3 AMP. COMPRESS VALUE (V) ERROR (%)
off/on Ch01/on Ch02 value value
4 AUX. GEN NONE
unless the optional Auxiliary Generator is fitted, in which case the
Display reads:
AUX. GEN RUN/STOP WAVEFORM sine/square/triangle
Note: CARRIER and MOD are not displayed; these will be as for Main
Generator. A further page is available for the Auxiliary
Generator.
5 AUX. GEN AMP (V) BIAS (V)
value value
ANALYZER 1 ANALYZERS STOP/RUN/IDLE/DELAY/WAIT* RUN TIME (sec)
AUTO-INT off/short on Ch01/short on Ch02 / value =
/long on Ch01/Iong on Ch02
*WAIT signifies that the Analyzer is ready, but waiting for another
section of the 1250.
=This value shows the time taken for the last measurement completed.
2 INT.TIME (sec/cyc) M. DELAY (sec/cyc) HARMONIC
value value 01
Note: HARMONIC will show a number from 1 to 16.
3 Ch RANGE DEMOD INPUT COUPLING
01 auto/30mV/ off/1 on/2 on front/rear DC/AC
300mV/3V/
30V/300V
4 Ch 02 as for Ch 01
Note: The Display will show only the Channel numbers of Analyzers
which are fitted. If additional Analyzers are present, the status of these
will be shown on subsequent pages, in the sequence: Ch11 to Ch18,
Ch21 to Ch28, Ch31 to Ch38, and Ch41 to Ch48.
