Command Reference
tinuous triggering (CONT) is approximately 1.5 per se-
cond at the SLOW setting, 8 per second at MED or 14 per
second at FAST. The RATE? query queries the selected
measurement speed.
RNGE(?) {i}
The RNGE command sets the measurement range and the
related source resistance:
i = 1: between 1 and 25 Ω;
i = 2: between 2 and 25 Ω;
i = 3: between 3 and 400 Ω;
i = 4: between 4 and 6.4 kΩ;
i = 5: between 5 and 100 kΩ;
i = 6: between 6 and 100 kΩ.
The RNGE? query queries the selected measurement
range.
RNGH(?) {i}
The RNGH command deactivates (i=0) or activates (i=1)
the manual measurement range selection. If the manual
measurement range selection is deactivated, the auto-
matic HM8118 measurement range selection is activated
(AUTO). The RNGH? query queries the status of the ma-
nual measurement range selection.
PMOD(?) {i}
Use the PMOD command and the parameter to select the
measurement function:
i=0
: AUTO
i=1
: L-Q
i=2
: L-R
i=3
: C-D
i=4
: C-R
i=5
: R-Q
i=6
: Z-Θ
i=7
: Y+Θ
i=8
: R+X
i=9
: G+B
i=10
: N+Θ
i=11
: M
The PMOD? query queries the selected measurement
function.
VOLT(?) {x}
The VOLT command sets the measurement voltage to x
volts. You can select any value between 0.05 V and 1.5 V
for x. Interim values will be rounded by 0.01 V to the nea-
rest figure. The VOLT? query queries the selected measu
-
rement voltage.
OUTP(?) {i}
The OUTP command sets the main measurement value
display for the measurement values to
Normal
(i=0),
If the automatic measurement range selection is activated, it is
not possible to perform relative measurements and measure-
ments with integrated binning interface.
relative measurement value deviation
%
(i=1) or
absolute measurement value deviation
(i=2).
The OUTP? query queries the status of the main measure-
ment value display.
PREL(?) {x}
The PREL command sets the parameter x to determine the
relative measurement value deviation (REF_M) for the main
measurement value display, if the measurement value de-
viation of the main measurement value display was previ-
ously activated via OUTP 1 or OUTP 2 command (DEV_M).
The PREL command generates an error message (ERROR),
if the automatic R&S®HM8118 measurement range selec-
tion (AUTO) is activated. The unit for x is:
Ohm:
For R+Q, Z+Θ and R+X measurements,
Henry:
For L+Q, L+R and M measurements,
Farad:
For C+D and C+R measurements and
Siemens:
For Y+Θ and G+B measurements.
The PREL? query queries the set value of the relative
measurement deviation (REF_M) of the main measurement
value display.
OUTS(?) {i}
The OUTS command sets the secondary measurement va-
lue display for the measurement values to
Normal
(i=0),
relative measurement value deviation
%
(i=1) or
absolute measurement value deviation
(i=2).
The OUTS? query queries the status of the secondary
measurement value display.
SREL(?) {x}
The SREL command sets the parameter x to determine
the relative measurement value display for the secon-
dary measurement value display (REF_S), if the secon-
dary measurement value display was previously activa-
ted via OUTS 1 or OUTS 2 command (DEV_S). This com-
mand generates an error message (ERROR), if the automa-
tic HM8118 measurement range selection (AUTO) or the M
measurement is activated (by means of the interference of
mutual inductance). The unit for x is:
Ohm:
For L+R, C+R and R+X measurements,
Degree:
For Z+Θ, Y+Θ and N+Θ measurements
and
Without unit:
For all other measurements.
The SREL? query queries the set value of the measure-
ment deviation (REF_S) of the secondary measurement va-
lue display.
CALL 0
The CALL 0 command determines the bridge settings and
ensures that the subsequent command (CROP or CRSH)
performs an open or short compensation for the fre-
quency that is currently set for the instrument. It is neces-
sary to first send CROP or CRSH before the compensation
is performed.
