Consult Section VIII, Service, for a detailed explanation of these diagnostic functions.
OF(d) Output Fault, outputs a decimal value that can be decoded to detieniilne
have occurred. These fault conditions are automatically accumulated by the HP 8340B/41B, and
are only cleared by an Instrument Preset or when the fault has been output following an OF
command. The outputted decimal number is interpreted at the bit level, where the bits are defined
as follows:
Bit 0:
Not used.
Bit 1:
Not used.
Bit 2:
N1 oscillator unlocked.
Bit 3:
N2 oscillator unlocked.
Bit 4:
YIG oscillator unlocked.
Bit 5.
HET oscillator unlocked.
Bit 6.
M/N oscillator unlocked.
Bit 7.
REF oscillator unlocked.
Bit 8.
Not used.
Bit 9.
Not used.
Bit 10:
LVC - preset of level control board failed.
Bit 11:
PEAK - peaking algorithm failed.
Bit 12:
ADC - ADC time out.
Bit 13:
KICK - YO or SYTM kick pulse time out.
Bit 14:
CAL - calibration data checksum incorrect.
Bit 15:
Not used.
If any of these fault conditions are encountered, consult the In Case of Difficulty section or Section
VIII (Service) for further instructions. A BASIC example:
100
OUTPUT 719; "OF"
110
ENTER 719; F
120
FOR N = 0 TO 15
130
PRINT "BIT"; N ; " = " ;BITCF , N>
140
NEXT N
Line 130 determines each bit of arbitrary variable F in the BIT(F,N) statement.
OI(19a) Output Identification, outputs the revision date of the firmware presently loaded into the HP
8340B/41B as:
08340BREV day month year
x
(2 numbers for the day, 3 letters for the month, and 2 numbers for the year)
A BASIC example:
10
DIMA$[191
100
OUTPUT 719; "01"
110
ENTER 719; A$
120
PRINT "FIRMWARE REVISION"; At
