1.0 Product description
The 4830B accelerometer simulator is a hand held battery operated signal generator designed specifically to
simulate the electrical output of common types of accelerometers. The instrument contains a highly accurate
oscillator with an adjustable output level and is ideal for setting up, testing and the diagnosis of faults within data
acquisition systems, FFT analyzers, environmental test systems or simply as a flexible signal generator.
The instrument provides AC output signals which mimic those of either voltage mode accelerometers (generic
IEPE, Isotron® types etc.) or charge mode accelerometers (both single ended and differential configurations).
The simulation outputs are conveniently scaled in units of acceleration, i.e. “g”, as mV/g (millivolt) or pC/g (picocoulomb) signals as appropriate, although the outputs can be configured to be proportional to units of velocity or
displacement. An auto-calculating on screen “Vibration Calculator” provides the user with corresponding values
in respect of m/s², ips, mils, mm and m/s based units.
The instrument also features a TTL compatible tachometer output which allows operators of condition monitoring
systems to set signal conditioning tracking filter center frequencies without the need to generate an external,
real time tachometer signal. The tachometer frequency is adjustable as a ratio of the respective output signal
frequency.
The 4830B also features the ability to analyze a vibration signal using a Fast Fourier Transfer function. This
allows a voltage proportional vibration signal to be inputted to the instrument thereby providing an indication of
both frequency and magnitude.
Simulation parameters can be selected, adjusted, and saved as a “profile” either by the front panel keypad or
using the supplied utility program. Use of the utility program not only allows profiles to be created and saved but
also organized into specific “profile sets” which can be conveniently stored on a PC. Up to 40 user profiles may be
downloaded to the simulator at any one time.

3.1. Menu structure
The simulatormenusare accessed via the three menu keys as shown in Figure 2below.
Figure 2: Menu structure
3.2. Home screen
The home screen is in two parts, upper and lower. When the simulator is turned on, the upper screen
becomes the default. This screen shows the “Profile” in use and an overview of the four primary simulation
parameters. The secondary parameters are shown in the lower screen. Moving between the upper and
lower screens is accomplished by pressing the up and down arrow keys. Pressing the
any point will return the display to the home screen.

3.3. Editing screen
The editing screenis accessed by pressing either the left or right arrow keys when in the home screen.
Similar to the home screen, the editing screens are in two parts, i.e. primary and secondary parameters.
Scroll up or down with the arrow keys to move between parameters and the upper and lower screens.
Move the cursor (inverted text) to the parameter that is to be edited, and select by pressing the

3.4. The “Profile”
A “Profile” is a set of parameters that combine to form the simulation. Parameters include:
• Signal frequency (Freq)
• Accelerometer sensitivity (Sens)
• Acceleration level (g)
• Waveform type (Type)
• Acceleration level (m/s2)
• Velocity (ips)
• Displacement (mils)
• Displacement (mm)
• Velocity (m/s)
• Ratio
In terms of simulating an accelerometer, the primary parameters are: sensitivity, acceleration level (g),
frequency and waveform type. These are displayed in the upper home screen. The secondary parameters,
other than ratio, are obtained by calculation, taking into account the frequency and acceleration level.
These secondary parameters are displayed in the lower home screen. The calculations are performed
automatically whenever a parameter is changed. Note: All profile parameters can be changed within the
IM4830B Rev B 9

edit screens. When a secondary parameter is changed the g level value will change as a result. See section
4.2.2for details.
3.4.1. Default profile
The default profile is loaded for convenience when the simulator is turned ON. The default profile
contains pre-set simulation parameters which cannot be permanently overwritten. All of the
parameters can be adjusted at the time (on the fly), but not saved. The default profile primary
parameters are:
• Frequency = 100Hz
• Sensitivity = 10.0000 (mV or pC)
• g level = 10.0000
• Type: Sinusoidal
3.4.2. User profile
The user can create a profile which contains specific simulation parameters, i.e. the parameters
are adjusted to meet the requirements of a particular test. A maximum of 40 profiles can be stored
within the simulator, each with a unique identification. Unlike the default profile, a user profile can
be edited and saved on the fly. See section 4.3for details on creating a “User profile”. Note:
Downloading a new profile set will erase any user profiles saved within the simulator.
3.4.3. Profile selection
Profile selection is accessed by pressing the PROFILESmenu key. Scroll up or down with the arrow
keys to move between profiles and select the profile required by pressing the ENTERkey.

3.5. Tools
Access to the tools menu is accomplished by pressing the TOOLSkey.

Scroll up or down with the arrow keys to move the cursor (inverted text) to the required field, and press the
ENTER key.
3.5.1. FFT
IM4830B Rev B 10
October 9, 2019
The simulator features a basic FFT (Fast Fourier Transfer) function. This feature allows users to
identify the fundamental frequency and order of magnitude, of a complex vibration or similar
waveform. The signal is inputted into the simulator using the shared Tach / FCN BNC connector.
The tachometer output function is disabled once FFT mode has been selected. Users should
