Syntax

DIAGnostic[:INFOrmation]:ADC? [<channel>]

Description

This query returns the latest values acquired by ADC (Analog-to-Digital Converter) of the currently selected channel.

Parameters

Name

Type

Range

Default

<channel>

Channel

CH1|CH2|CH3|CH4|CH5|CH6

n/a

Return

Return a list of quoted strings. The U_SET and I_SET are values measure on DAC outputs, and U_MON and I_SET on the channel output terminals.

Syntax

DIAGnostic[:INFOrmation]:CALibration? [<channel>]

Description

This query returns a list of calibration parameters for the currently selected channel. If the selected channel is in the calibration mode (CALibration[:MODE] ON) then all calibration information collected to the current calibration step will be returned. Otherwise the calibration data stored in non-volatile memory will be returned.

Parameters

Range

Default

<channel>

Channel

n/a

Return

The information will be returned as a list of quoted strings.

Usage example

Calibration parameters for BB3 when the channel 2 is not in the calibration mode:

DIAG:INFO:CAL? CH2

"remark=20200123 cert", "u_cal_params_exists=1", "u_min_level=0.15V", "u_min_data=0.08V", "u_min_adc=0.114V", "u_mid_level=20V", "u_mid_data=20.597V", "u_mid_adc=19.9685V", "u_max_level=38V", "u_max_data=39.192V", "u_max_adc=37.973V", "u_min_range=0V", "u_max_range=40V", "i_5A_cal_params_exists=1", "i_5A_min_level=0.05A", "i_5A_min_data=0.0405A", "i_5A_min_adc=0.03695A", "i_5A_mid_level=2.425A", "i_5A_mid_data=2.4757A",

"i_5A_mid_adc=2.4125A", "i_5A_max_level=4.8A", "i_5A_max_data=4.9122A", "i_5A_max_adc=4.78855A", "i_5A_min_range=0A", "i_5A_max_range=5A", "i_50mA_cal_params_exists=1", "i_50mA_min_level=0.0005A", "i_50mA_min_data=0.00041A", "i_50mA_min_adc=0.000371A", "i_50mA_mid_level=0.02425A", "i_50mA_mid_data=0.02545A", "i_50mA_mid_adc=0.0240945A", "i_50mA_max_level=0.048A", "i_50mA_max_data=0.05052A", "i_50mA_max_adc=0.047887A", "i_50mA_min_range=0A", "i_50mA_max_range=0A"

The query results when a channel is just entered the calibration mode:

DIAG:INFO:CAL?

"u_level=none", "i_level=none"

The query results when a channel is at the step MIDdle of the voltage calibration:

DIAG:INFO:CAL?

"u_min=0.11V", "u_level=mid", "u_level_value=24.05V", "u_adc=24.14V", "i_level=none"

Return

The information will be returned in the following format: "<return code, device name, installed, return message>" where the return code could be one of the following values:

• 0 – not installed or recognized
• 1 – failed
• 2 – passed
• 3 – testing
• 4 – skipped
• 5 – warning

This information format will repeat with as many iterations as the number of devices found in configuration parameters of the BB3.

Usage example

Return self-test results when SD card is not found:

DIAG:TEST?

"2, EEPROM, installed, passed", "2, SD card, installed, passed", "2, Ethernet, installed, passed", "2, RTC, installed, passed", "2, DateTime, installed, passed", "2, Fan, installed, passed", "2, AUX temp, installed, passed", "2, CH1 temp, installed, passed", "2, CH2 temp, installed, passed", "2, CH3 temp, installed, passed", "2, CH4 temp, installed, passed", "2, SLOT1, installed, passed", "2, SLOT2, installed, passed",

"2, SLOT3, installed, passed"

Check status of specified device, e.g. channel 2:
