Section 13 : Order Domain Results in List Mode

Machinery run-ups and run-downs can be analyzed with order analysis, which is spectral analysis normalized to RPM. Results can be simplified by examining only a list of amplitude versus order, so that only desired results are examined.

To set up and measure a list of 10 orders for a machinery run-up, follow these steps:

Press the green [Preset] hardkey

Press [DO PRESET] softkey (F1).

Press the [Pause/Cont] hardkey if desired.

Press the [ORDER ANALYSIS] softkey (F3).

Press [CHANNELS 1 2 4 ] softkey (F7) until 1 is highlighted.

Press the [Input] hardkey

Press the [CH1 AUTO UP ONLY] software (F5).

Order analysis requires a tachometer signal connected to the TACH BNC at the back of the analyzer. To set up the AGILENT 35670A for the tachometer signal, follow these steps:

Press the [TACHOMETR SETUP] softkey (F9).

Toggle the [TACH DISP ON OFF] softkey (F6) until ON is highlighted.

Press the [TACH PULS PER REV] softkey (F1).

Enter the number of tachometer pulses per shaft revolution and press the [ENTER] softkey (F1).

Press the [LEVEL] softkey (F3).

Enter the tachometer level and press the [ENTER] softkey (F1).

If in doubt about the tachometer level, enter 0.5 V and experiment with level, slope, and trigger range until a tachometer display is shown.

Prepare the order display as follows:

Press the [Disp Format] hardkey.

Press the [UPPER/LOWER] softkey (F3).

Press the [Active Trace] hardkey.

Press the [B] softkey (F1)

Prepare the order results list as follows:

Press the [Analys] hardkey.

Press the [DATA TABLE] softkey (F5).

Toggle the [TABLE ON OFF] softkey (F1) until ON is highlighted.

Press the [INSERT X VALUE] softkey (F4).

Enter 1 and press the [ORDERS] softkey (F1).

Enter 2 and press the [ORDERS] softkey (F1).

Enter 3 and press the [ORDERS] softkey (F1).
