Appendix E, ALPHABETICAL LISTING OF COMMANDS
E-21
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
When the fast analog output mode and noise measurement mode are turned off
(FASTMODE 0 and NOISEMODE 0), the selection is according to the following
table:
n Slope
0 6 dB/octave
1 12 dB/octave
2 18 dB/octave
3 24 dB/octave
When:
a) The fast output filter mode is turned on, or
b) Noise measurement mode is turned ON (NOISEMODE 1)
the selection is according to the following table:
n Slope
0 6 dB/octave
1 12 dB/octave
SNMASK [n1 n2 n3 n4] Ethernet Subnet Mask
When this command is sent without parameters, the instrument responds with the
current subnet mask e.g. 255.255.0.0
When sent with the four parameters, the command sets the subnet mask that will be
used when the model 7230 is set to static IP address mode (via the rear panel Config
Switch 2, see section 4.2.07)
The parameters are separated by a space character and not by a dot, e.g.
SNMASK 255 255 0 0
sets the subnet mask to 255.255.0.0
Note that the setting can be overridden if the IP address is set using the IPADDR
command.
SRATE[.] [n] Oscillator frequency and amplitude sweep step rate
In fixed point mode, sets the sweep rate in milliseconds per step, and in floating
point mode sets the rate in seconds. The range of n is 1 to 1000000 (1 ms to 1000 s)
ST Report status byte
Causes the lock-in amplifier to respond with the status byte, an integer between 0
and 255, which is the decimal equivalent of a binary number with the following bit-
significance:
