FAQ 2012-10-17

How to calculate the bit clock frequency under DSI interface of U8903A?
The Bit clock frequency can be calculated by multipling the number of channels,bit length and frame clock frequency.

FAQ 2012-08-25

What is the maximum bit clock cycle per frame for DSI interface of U8903A?
64 bit clock cycle per frame.

FAQ 2012-07-25

How do I perform WCDMA Power Control measurements on the E4406A or PSA Series Spectrum Analyzers?
Reverse link power control measurements can be made using the W-CDMA (Option BAF) power control measurement. Power control analysis on the downlink can be done in the Code Domain Power measurement using the Symbol Power vs. Time view.

FAQ 2012-05-28

Does the E4406A or PSA Series support GPRS measurements?
Both the E4406A and PSA Series support GPRS measurements. For the E4406A, option BAH (GSM) or option 202 (EDGE with GSM) are required. For the PSA, option 202 (GSM with EDGE) and option B7J (Digital Demodulation hardware) are required.

FAQ 2012-05-28

Does the E4406A or PSA Series Spectrum Analyzer provide GSM trigger to time zero (T0) timing in order to test Enhanced Observed Time Difference Tec...
Yes, the EDGE / GSM measurement personalities for the E4406A and PSA Series provide precise nanosecond timing between an external trigger and the training sequency T0 transition point. (click here for more details).

FAQ 2012-05-28

Why do I get a Meas Uncal message when I select either the Quasi-Peak or EMI Average detector for taking a full band sweep with the MXE EMI Receiver?
Sweeptime has reached its maximum. See complete FAQ for further details...

FAQ 2012-05-10

Each of the HSA products supports field strength measurements.

FAQ 2012-03-02

What is the frequency coverage of the handheld spectrum analyzers?
The frequency of the HSA varies by model.

FAQ 2012-03-01

How do I make spectrum analysis measurements on signals above 50 GHz using a PSA Series Spectrum Analyzer (E4440A, E4446A, E4448A)?
The PSA offers an option (AYZ) enabling the use of external millimeter harmonic mixers.

FAQ 2012-02-28

How can I measure the Channel Power of my signal on a PSA or ESA with the Max Hold function on?
The Band Power marker function may be used to make this measurement.

FAQ 2012-02-28

For my X-Series Signal Analyzer, how much of a difference should I see when changing the Input Z Correction from 50 to 75 ohms when in a dBmV scale?
When the input Z correction is toggled to 75 ohms, you will see a 1.76 dB higher result, which is 10 times the log of the ratio of input impedances

FAQ 2012-02-28

Do I need to buy an LO amplifier to make external mixer measurements with my PSA Series Spectrum Analyzer?
An LO amplifier is not required. The LO out of the PSA is optimized to give excellent performance from the11970 or 11974 Series harmonic mixers.
