The MEAS key is used for complex measurement functions as power measurements,
occupied bandwidth, signal statistic, carrier to noise spacing, AM modulation depth,
third-order intercept point, harmonics and spurious emissions. For measurement
examples refer to the Quick Start Guide, "Basic Measurement Examples".
The following measurements can be performed:
●
Channel power and adjacent-channel power with span > 0 and with a single or sev-
eral carriers ("CH Power ACLR" softkey, for details see
Chapter 6.1.1.2, "Measur-
ing Channel Power and Adjacent-Channel Power" , on page 201)
●
Carrier-to-noise ratio ("C/N C/NO" softkey, for details see Chapter 6.1.1.3, "Mea-
suring the Carrier-to-Noise Ratio" , on page 225)
●
Occupied bandwidth ("OBW" softkey, for details see Chapter 6.1.1.4, "Measuring
the Occupied Bandwidth" , on page 228)
●
Spectrum Emission Mask measurements ("Spectrum Emission Mask" softkey, for
details see
Chapter 6.1.1.5, "Measuring with Spectrum Emission Masks" ,
on page 232)
●
Spurious Emissions measurements ("Spurious Emissions" softkey, for details see
Chapter 6.1.1.6, "Measuring Spurious Emissions" , on page 259)
●
Power in zero span ("Time Domain Power" softkey, for details see Chapter 6.1.1.7,
"Measuring the Power in Zero Span" , on page 270).
●
EMI Measurement softkey, for details see Chapter 6.1.1.8, "Performing EMI Mea-
surements" , on page 273
●
Amplitude probability distribution ("APD" and "CCDF" softkeys, for details see
Chapter 6.1.1.9, "Calculating Signal Amplitude Statistics" , on page 282)
●
3rd order intercept ("TOI" softkey, for details see Chapter 6.1.1.10, "Measuring the
Third Order Intercept Point (TOI)" , on page 301)
●
Modulation depth ("AM Mod Depth" softkey, for details see Chapter 6.1.1.11, "Mea-
suring the AM Modulation Depth" , on page 307)
●
Harmonic Distortion measurements ("Harmonic Distortion" softkey, for details see
Chapter 6.1.1.12, "Measuring Harmonic Distortion" , on page 308)
To open the power measurement menu
●
Press the [MEAS] key.
The measurement menu for spectrum analysis is displayed (see
Chapter 6.1.1.1,
"Softkeys of the Power Measurement Menu" , on page 198).
6.1.1.1 Softkeys of the Power Measurement Menu
The following table shows all softkeys available in the power measurement menu. It is
possible that your instrument configuration does not provide all softkeys. If a softkey is
only available with a special option, model or (measurement) mode, this information is
provided in the corresponding softkey description.
