Configure the 1444 Dynamic Measurement Module Chapter 3
Personality Module Personality defines the general measurement configuration of the module,
including which channels are used, at what maximum frequency (or DC).
Two categories of Personality are provided – Real-Time and Multiplexed. Real-Time
personalities provide continuous measurements that update at rates of not slower
than once every 40 milliseconds. The Multiplexed personalities update measurements
in channel pairs, although they do not necessarily alternate equally (see Time Slot
Multiplier).
The available selections are as follows.
1: Real Time, 4 Ch – Dynamic (4 kHz) or Static
All channels are available. Each channel pair can be defined for either Static (DC) or
Dynamic (AC) measurements. Dynamic channels can be configured for an Fmax up to
4578 Hz (274.7 kCPM).
2: Real Time, 2 Ch – Dynamic (20 kHz), 2 Ch Static
Channels 0 and 1 can be configured for Dynamic (AC) measurements with an Fmax of
up to 20.6 kHz (1236 kCPM). Channels 2 and 3 can be used for Static (DC)
measurements.
32: Real Time, 4 Ch – Dynamic (4 kHz) – Dual Path
For measurements, this is the same as “1: Real Time, 4 Ch – Dynamic (4 kHz) or
Static”. What is different is that the module internally connects the channel 0 and 2
inputs and the channel 1 and 3 inputs.
64: Real Time, 2 Ch – Dynamic (40 kHz)
Channels 0 and 1 (pair) can be configured for Dynamic (AC) measurements with a
measurement Fmax of 40 kHz*, or as gSE. Channels 2 and 3 are disabled (off).
-128: Multiplexed, 4 Ch – Dynamic (40 kHz) or Static – Paired
Channels can be configured in pairs (0 and 1, 2 and 3) for Dynamic (AC)
measurements with a measurement Fmax of 40 kHz*, as gSE, as Static (DC)
measurements, or off.
Channel Pair measurements alternate based on the Time Slot Multiplier setting.
* The 40 kHz personality provides high frequency overall and gSE measurements. The
maximum possible FFT FMAX available from a 40 kHz personality is 2747 Hz (164.8
kCPM).
