NOTE: At least one of the curves selected for storage in the curve buffer must be
chosen from those marked with an asterisk(*) in the above table.
[n ] Analog output control
1 2
Defines what outputs appear on the CH1 and CH2 connectors on the rear panel.
When the fast analog output mode is turned off (FASTMODE 0), the selection is
according to the following table:
n Signal
2
0 X % (2.5 V FS)
1 Y % (2.5 V FS)
2 Magnitude % (2.5 V FS)
3 Phase 1: +9 V = +180°, -9 V = -180°
4 Phase 2: +9 V = 360°, - 9 V = 0°
5 Noise % (2.5 V FS)
6 Ratio: (10 × X%/ADC 1)
(10 × X%/ADC1)
7 Log Ratio: log

8 Equation 1
9 Equation 2
Dual modes only:-
10 X2 % (2.5 V FS)
11 Y2 % (2.5 V FS)
12 Magnitude2 %FS
13 Phase2 1: +9 V = +180°, -9 V = -180°
14 Phase2 2: +9 V = 360°, -9 V = 0°
n is compulsory and is either 1 for CH1 or 2 for CH2
1
Note: n = 5 is only permitted if the noise measurement mode is on
2
(NOISEMODE 1) or if the present settings of output filter slope and time constant
are within the permitted range and the synchronous time constant control is off.
When the fast analog output mode is turned on (FASTMODE 1) and the instrument
is in single or virtual reference mode, the selection is according to the following
tables:
n = 1 (i.e. CH1 output)
1
n Signal
2
0 X % (2.5 V FS)
n 2 (i.e. CH2output)
1
n Signal
2
1 Y % (2.5 V FS)
2 Magnitude % (2.5 V FS)
When the fast analog output mode is turned on (FASTMODE 1) and the instrument
is in dual harmonic or dual reference mode, the selection is fixed according to the
following tables:
