Section 4

: 

Range, Digits, Rate, Bandwidth, and Filter

 

Series 3700 System Switch/Multimeter Reference Manual

 

 

4-6 

Document Number: 3700S-901-01 Rev. A / August 2007 

 

 

 

Bandwidth 

There are three bandwidth settings for ACV and ACI measurements. The RATE setting 
determines the bandwidth setting as follows: 

 

SLOW: 3Hz to 30Hz 

 

MEDium: 30Hz to 300Hz 

 

FAST: 300Hz to 300MHz 

When the SLOW bandwidth (3Hz to 30Hz) is chosen, the signal goes through an analog RMS 
converter. The output of the RMS converter goes to a fast (1kHz) sampling A/D and the RMS 
value is calculated from 1200 digitized samples (1.2s). 

When the MEDium bandwidth (30Hz to 300Hz) is chosen, the same circuit is used. However, 
only 120 samples (120ms) are needed for an accurate calculation because the analog RMS 
converter has turned most of the signal to DC. 

In the FAST bandwidth (300Hz to 300kHz), the output of the analog RMS converter (nearly pure 
DC at these frequencies) is simply measured at 1 PLC (16.6ms). For remote programming, the 
integration rate can be set from 0.0005PLC to 12PLC or 15PLC. 

To achieve the best accuracy for ACV and ACI measurements, use the bandwidth setting that 
best reflects the frequency of the input signal. For example, if the input signal is 40Hz, then a 
bandwidth setting of 30 should be used. 

NOTE

 

A rate command (

dmm.nplc

 (on page 9-105) or 

dmm.aperture

 (on page 9-70)) for ACV 

and ACI is only valid if the bandwidth for that AC function is set to 300 (300Hz to 
300kHz). Bandwidth is set using the dmm.detectorbandwidth ICL command or 
DETECTBW menu option under the function's attribute menu). 

 

Filter 

The digital filter is used to stabilize noisy measurements. The displayed, stored, or transmitted 
reading is a windowed-average of a number of reading conversions (from 1 to 100).  

The filter setup is ―remembered‖ and can be unique for each measurement function (DCV, ACV, 
DCI, ACI, Ω2, Ω4, CSΩ, and TEMP). When you select a function, the instrument will return to 
the last filter setup for that function. 

NOTE 

The various instrument operations, including Filter, are performed on the input signal 
in a sequential manner
