  • Page 17: Dc Amplitude

    CHANNEL A – DC AMPLITUDE SET UP Channel A of the 1510A may be programmed for either AC voltage or DC voltage outputs. Additionally, a DC offset or bias may be applied to the Channel A output voltage signal. The following is an example of how to program Channel A for a DC Voltage output of 5.00 Volts.

  • Page 18: Frequency

    When Channel B is programmed to simulate a speed signal, there are many more options: PULSE MODE – Channel B of the 1510A can be programmed to produce a single pulse occurring at the same frequency or at a ratio of the Channel A frequency.

  • Page 19: Voltage Amplitude

    CHANNEL B – VOLTAGE AMPLITUDE SET UP Channel B of the 1510A may be programmed for either voltage or special speed signals. The following is an example of how to program Channel B to create a 5.000 Volts RMS Sine wave output.

  • Page 20: Frequency

    CHANNEL B – FREQUENCY SET UP The 1510A can produce a signal ranging from 1 Hz to over 50 KHz. To program Channel B to produce a signal of 250Hz, perform the following steps: Press the ChB Channel Setup selector button...

  • Page 21: Waveform

    CHANNEL B WAVEFORM FUNCTION SET UP Channel B of the 1510A can produce either a normal signal waveform, a single pulse at a specific frequency, or it can synthesize complex tachometer signals. Channel B of the 1510A can be programmed for 1 of four different waveforms in the waveform mode.

  • Page 22: Ratio Frequency

    CHANNEL B – RATIO FREQUENCY SET UP The 1510A can produce a signal on Channel B whose frequency is a RATIO of the Channel A signal frequency. This is useful when trying to simulate one signal on channel B while maintaining a fixed relationship with the frequency of the signal being generated by Channel A.

  • Page 23: Pulse Set Up

    CHANNEL B PULSE SET UP The 1510A can produce a bi-polar or “TTL” style PULSE function on Channel B which can be used to simulate a “key-phaser” signal, or similar type of machinery speed signal typically used as a once-per-revolution (1/rev) signal.

  • Page 24: Tachometer Set-Up

    CHANNEL B TACHOMETER SET UP The 1510A can produce an odd-tooth tachometer signal to simulate speed signals with “embedded” 1/revolution pulses which are found on many modern gas turbine engines. The “embedded” of “odd-tooth” signal may be programmed with a larger or a smaller amplitude than the other pulses in the signal.

  • Page 25: Jog Function

    JOG FUNCTION Often, it is desirable to repeatedly change one of the 1510A output values by just a small amount. To make this easy, the 1510A features a JOG function where users may repeatedly change a single parameter in small steps.

  • Page 26: Phase Function

    PHASE FUNCTION Often, it is desirable to change the phase relationship between the Channel A and Channel B output signals.

The following illustrates how to change the Phase Angle between the Channel A signal and the Channel B signal to 90 degrees.

  • Page 27: Frequency Sweep Operation

    To create a simulated deceleration, define the ending frequency to be lower than the starting frequency. Sweep Duration – This is the length of time the 1510A will take to go from the starting frequency to the ending frequency. The time is entered as seconds.

  • Page 28: Bridge Function

    BRIDGE FUNCTION The 1510A can be programmed to produce low level DC voltages to simulate those produced by bridge type sensors such as load cells and strain gauges. This function allows users to calibrate measurement systems with high-accuracy low level signals.
  • Page 29 NOTE For highest accuracy in Bridge Mode, ensure that cables are as short as possible and that no dissimilar metals are used in cables and connectors. At very low signal amplitudes, dissimilar metals can cause false readings due to galvanic interaction. 7001-0019 Revision 3.0 Page 24...
