A 2.2.3.2 Timer Pulse Width
TIMERPULSEWIDTHn <Pulsewidth>
n = 1 ... 3 for the timer 1 to 3
Pulse width modulation of a timer cycle.
Determines the pulse width modulation of the timer signal; that is, the ratio of high to low
portions of the timer signal in percent.
Pulse width modulation can be set between 0 (0 %) and 1 (100 %). Three decimal points
are permitted. Internally, IF2008/ETH selects the next possible supported pulse width
modulation.
A pulse width modulation of 0.5 means that the high and low portions of the timer signal
have the same lengths. A pulse width modulation greater than 0.5 means that the high
portion of the timer signal is longer than the low portion. A pulse width modulation small-
er than 0.5 means that the high portion of the timer signal is shorter than the low portion.

F = Timer frequency
TH = Timer signal high
TL = Timer signal low
Timer pulsewidth = PW / (TH + TL)

A 2.2.4 Parameter Management
A 2.2.4.1 Save Parameters
STORE 1|2|3|4|5|6|7|8
Save the current parameters under the specified number in the flash memory of
IF2008/ETH.
A 2.2.4.2 Read Parameters
READ ALL|DEVICE|MEAS 1|2|3|4|5|6|7|8
Read the parameters under the specified number from the flash memory of IF2008/ETH.
The volume of data to be loaded must also be specified:
- ALL: All parameters are loaded.
- DEVICE: Only the basic device settings are loaded (interface parameters).
- MEAS: Only the measurement settings are loaded (all properties for the measure-
ment).
A 2.2.4.3 Factory Settings
SETDEFAULT [ALL] [NODEVICE]
Reset to factory settings
- ALL: All setups are reset to factory settings. If ALL is not specified, only the current
setup is reset.
- NODEVICE: Only the settings for measurements are reset, the settings for interfaces
are maintained.
