SEN[.] [n]
Full-scale sensitivity control
The value of n sets the full-scale sensitivity according to the following table,
depending on the setting of the IMODE control:
n
IMODE=0
4
20 nV
5
50 nV
6
100 nV
7
200 nV
8
500 nV
9
1 µV
10
2 µV
11
5 µV
12
10 µV
13
20 µV
14
50 µV
15
100 µV
16
200 µV
17
500 µV
18
1 mV
19
2 mV
20
5 mV
21
10 mV
22
20 mV
23
50 mV
24
100 mV
25
200 mV
26
500 mV
27
1 V
Floating point mode can only be used for reading the sensitivity, which is reported in
volts or amps. For example, if IMODE = 0 and the sensitivity is 1 mV the command
SEN would report 18 and the command SEN. would report +1.0E-03. If IMODE was
changed to 1, SEN would still report 18 but SEN. would report +1.0E-09.
SLOPE [n]
Output low-pass filter slope (roll-off) control
The value of n sets the slope of the output filters according to the following table:
n
slope
0
6 dB/octave
1
12 dB/octave
2
18 dB/octave
3
24 dB/octave
SRATE[.] [n]
Oscillator frequency sweep step rate
Sets the sweep rate in time per step in the range 50 ms to 1000 s, in 5 ms increments.
