Instrument Identification

The instrument is delivered from the factory with the Model Number, Instrument Description, and the Serial Number. You can change the Model Number and Serial Number in the Preferences tab in the System menu. The Description will be automatically selected based on Model Number.

Attenuator Compatibility Mode

Remote command only.

Configures the Attenuator Compatibility Mode. When in PSG mode, the coupling among Power, Attenuation, and ALC Level works in a similar way as the PSG. With this coupling, the Power is changed when the ALC Level is changed. In the MXG, Power is not clipped when the ALC Level goes to either max or min.

The following example shows how Power, Attenuation, and ALC Level change when Attenuator Compatibility Mode is PSG.

# Set Attenuator Compatibility Mode to PSG

-> :SYSTem:COMPatibility:POWer:ATTenuator PSG

# Set up the initial condition. ALC Level is set based on

-> :POWer -10dBm

-> :POWer:ATTenuation:AUTO OFF

-> :POWer:ATTenuation?

<- 0

-> :POWer:ALC:LEVel?

<- -10

# Increasing ATTen by 10 dB decreases Power by the same amount

# -20 dBm (= ALC Level - Atten)

-> :POWer:ATTenuation 10.0 dB

-> :POWer?

<- -20

-> :POWer:ALC:LEVel?

<- -10

# Change ALC Level changes Power

-> :POWer:ALC:LEVel -9 dBm

-> :POWer?

<- -19

# When Auto Atten is on (Atten Hold off), the equation

#  Power = ALC Level - Atten

# doesn't hold.

# Note that Atten 70 dB in this example isn’t the actual Atten value.

# In MXG, the actual one is set only when Auto Atten is off. 

-> :POWer:ATTenuation:AUTO ON

-> :POWer?

<- -19

-> :POWer:ATTenuation?

<- 70

-> :POWer:ALC:LEVel?

<- -9

# Changing Power doesn't change Atten nor ALC Level

-> :POWer -17.0 dBm

-> :POWer:ATTenuation?

<- 70

-> :POWer:ALC:LEVel?

<- -9

# When AUTO is off again, Atten and ALC Level are set to satisfy the equation.

#  Power = ALC Level - Atten

-> :POWer:ATTenuation:AUTO OFF

-> :POWer?

<- -19

-> :POWer:ATTenuation?

<- 0

-> :POWer:ALC:LEVel?

<- -19

# When Power changes by a large amount, ALC Level exceeds the limit.

# In PSG, the both the power and ALC Level are clipped.

# On the other hand, in MXG, only ALC Level is clipped.

-> :POWer -37.0 dBm

-> :POWer:ATTenuation?

<- 0

-> :POWer:ALC:LEVel?

<- -20

-> :POWer?

<- -37

-> :SYST:ERR?

<- -222,"Data out of range;ALC Level value clipped to lower limit -20 dBm."

Enable SCPI Development Mode

When the instrument is in remote operation, a message box appears on the screen to notify the operator that an external program is controlling the instrument.  In some situations, such as during development of SCPI programs, you may want to see the full instrument screen.  This SCPI command is available to suppress the on-screen remote operation notification.

Suppress SCPI Compatibility Errors

For N5185A/N5186A, allows sending the[:SOURce][:RF<channel>]:POWer:ALC[:STATe] and [:SOURce][:RF<channel>]:POWer:ALC:SEARch SCPI commands without generating an error. No RF Output operation changes as this instrument does not contain an ALC or perform Power Search. This preference can be used to allow programmatic compatibility with other Keysight Technology signal generators.

Allow Remote Browser Access

Enables or disables access to the user interface from a remote browser. See Remote Access via Web Browser to know more.

Change Password

Allows you to change the password for accessing the instrument remotely via a Web browser. See Remote Access via Web Browser to know more.

The password can be changed from any logged in remote browser, or directly from the instrument’s front panel in the Settings menu, under Preferences.

Password requirements:

• minimum 8 characters in length

• must contain at least one lowercase letter

• must contain at least one uppercase letter

SCPI Backwards Compatibility Mode

Optimizes SCPI backwards compatibility with legacy products by coercing queries to return deprecated values.

• E82x7D: Compatibility for E8257D, E8267D, and E8257N.

• E8663D: Compatibility for E8663D.

• N51xxB: Compatibility for N5166B, N5171B, N5172B, N5173B, N5181B, N5182B, and N5183B.
