Key Sequence: Shift > Measure (4) key > Power and Bandwidth > ACPR

SPA ACPR Menu

On/Off Begins or ends the ACPR measurement. Main Ch BW Sets the bandwidth of the main channel for ACPR measurement. Use the keypad, the directional arrow keys, or the rotary knob to enter a specific frequency. When using the keypad, press the GHz, MHz, kHz, or Hz submenu key to accept the frequency input. Changing this value automatically changes the adjacent channel bandwidth and channel spacing. Adj/Alt Ch BW Sets the bandwidth of the adjacent channels for ACPR measurement. Use the keypad, the directional arrow keys, or the rotary knob to enter a specific frequency. When using the keypad, press the GHz, MHz, kHz, or Hz submenu key to accept the frequency input. Ch Spacing Sets the channel spacing between the main and adjacent channels. Use the keypad, the directional arrow keys, or the rotary knob to enter a specific frequency. When using the keypad, press the GHz, MHz, kHz, or Hz submenu key to accept the frequency input. This value must be greater than or equal to half of the main channel bandwidth, plus half of the adjacent channel bandwidth. The up or down arrows change the frequency by the frequency step size entered in the Freq (Frequency) Menu. The left or right arrow keys change the value by 10% of the span. Span Sets the span for ACPR measurement. Use the keypad, the directional arrow keys, or the rotary knob to enter the span. Back Returns to the Power and BW Menu.

Emission Mask Menu

Key Sequence: Shift > Measure (4) key > Masks and C/I > Emission Mask

Emission Mask Menu

This submenu controls the setup and display of the emission mask. The emission mask is an upper segmented limit line. It must have more than two nodes, which mean at least two segments. The spectrum emission mask measurement includes the in-band and out-of-band emissions.   Emission Mask On/Off Turns On/Off the Emission Mask graph and table display. Note: Before turning Emission Mask on, you must have created or recalled a limit line. Recall Limit as Emission Mask Opens the recall menu for selecting a limit line for use as the Emission Mask. Ref Power Peak/Channel Press to display the Reference Power as Peak or Channel. When Channel is selected, the Reference Power value is the integral of the individual peaks within the channel. Channel Width Channel Width is preset within the Signal Standard. Use this button to adjust the width as desired. Peak Markers On/Off Turning on this feature displays a peak marker within an Emission Mask segment. For example, if the Emission Mask had seven segments then there would be seven peak markers. Back   Returns to the Masks and C/I Menu.

Key Sequence: Shift > Measure (4) key > Masks and C/I > C/I

C/I Menu

On/Off Turns carrier to interference ratio measurements on or off. Center Freq Press this submenu key to set the center frequency or the offset center frequency. Use the Arrow keys or the rotary knob, then press Enter. Or use the number keypad, then press a unit key or press Enter for values in MHz. With zero offset, this key displays the title Center Freq. With an offset other than zero, this key displays the title Offset Center Freq, as shown below the full menu. Refer to Frequency Menu (Freq 1/2) with Offset Function. Span Press this submenu key to set the frequency span. Use the Arrow keys or the rotary knob, then press Enter. Or use the number keypad, then press a unit key or press Enter for values in MHz. Carrier Signal Type Press this submenu key to display the C/I Signal Type Menu. Min Sweep Time Press this submenu key to set the sweep time. The minimum valid sweep time is displayed on the key. (The minimum valid sweep time is dependent on other settings, such as RBW and VBW.) Use the Arrow keys or the rotary knob, then press Enter. Or use the number keypad, then press a unit key or press Enter for values in µs. Back Returns to the Masks and C/I Menu.   Offset Center Freq Submenu key label when a frequency offset has been entered.

C/I Signal Type Menu

After you select a signal type, by pressing a submenu key, the C/I Menu is automatically displayed. This is the default behavior even if you press the active key (with the red circle displayed).   NB FHSS Press this submenu key to set Narrowband Frequency Hopping Spread Spectrum as the interfering signal type. WB FHSS Press this submenu key to set Wideband Frequency Hopping Spread Spectrum as the interfering signal type. Broadband Press this submenu key to set Broadband (such as CDMA or GSM) as the interfering signal type.     Back Returns to the C/I Menu. without changing the currently‑selected signal type.

 

AM/FM Demod 1/2 Menu

Key Sequence: Shift > Measure (4) key > AM/FM Demod

SPA AM/FM Demod 1/2 Menu

On/Off Turns AM/FM Demodulation on or off. Demod Type Provides submenu keys to select the type of signal to be demodulated (refer to Demod Type (AM/FM) Menu): FM Wide Band FM Narrow Band AM USB LSB Demod Freq Use the keypad, the directional arrow keys, or the rotary knob to enter the center frequency of the signal to be demodulated. This frequency does not have to be within the current frequency sweep range to which the instrument is set. Demod Time Use the keypad, the directional arrow keys, or the rotary knob to increase or decrease the demodulation time, and press the Enter key to select. The demodulation time can be set from 100 milliseconds to 500 seconds. The instrument sweeps one time for every demodulation period. Sweeping pauses during the demodulation time. Set Demod Freq to Current Marker Freq Sets the demodulation frequency to the frequency of the current marker. Volume The current volume setting is displayed on the screen. Use the up or down arrow keys or rotary knob to change the volume, and press the Enter key to select. More Press this submenu key to display the AM/FM Demod 2/2 (More) Menu. Back Returns to the Measure Menu.
