SENSe:FILTer:TIMe
Description:
Set or return the current length of the integration filter on the selected channel. If the filter
state is set to AUTO, querying the time will return -0.01, and if set to OFF, a time query will
return 0.00. Note that setting the filter time will force the state to ON.
Syntax:
SENSe[1|2]:FILTer:TIMe <n>
Argument:
<n> = 0.01 to 15.00 seconds
Valid Modes:
CW and Modulated modes
SENSe:BANDwidth
Description:
Set or return the sensor video bandwidth for the selected sensor. HIGH is the normal
setting for most measurements. The actual bandwidth is determined by the peak sensor
model used. For 57000 series peak sensors the LOW video bandwidth is less than 500 kHz
to allow calibration at 50 MHz. Use LOW bandwidth for additional noise reduction when
measuring CW or signals with very low modulation bandwidth. If LOW bandwidth is used
on signals with fast modulation, measurement errors will result because the sensor cannot
track the fast changing envelope of the signal.
Syntax:
SENSe[1|2]:BANDwidth <asc>
Argument:
<asc> = LOW, HIGH
Valid Modes:
Peak sensors only
SENSe:IMPEDance
Description:
Set or return voltage probe sensor impedance for power calculations for the selected chan-
nel. Characteristic impedance is used only for voltage to power conversions. This can be
used to calculate and display power from a voltage measurement across a load impedance
using a voltage probe.
Syntax:
SENSe[1|2]:IMPEDance <n>
Argument:
<n> = 10 to 2500 ohms
Valid Modes:
Voltage probes only
SENSe:CORRection:OFFset
Description:
Set or return a measurement offset in dB for the selected sensor. This is used to compensate
for external couplers, attenuators or amplifiers in the RF signal path ahead of the power
sensor. In the main TEXT display, a small triangle (delta symbol) will appear above the units
if the offset is not set to zero.
Syntax:
SENSe[1|2]:CORRection:OFFset <n>
Argument:
<n> = -100.00 to 100.00 dB
Valid Modes:
Any
