Comment
Module Personality defines the general measurement configuration of the module,
Personality
including which channels are used, at what maximum frequency (or DC).
Two categories of Personality are provided – Real-Time and Multiplexed. Real-Time
1
personalities provide continuous measurements that update at rates of not slower
than once every 40 milliseconds. The Multiplexed personalities update measurements
2
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
64
All channels are available. Each channel pair can be defined for either Static (DC) or
-128
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).
