Message

Explanation

(ERR? query)

(ERR key)

 

 

 

 

0

NO ERROR

Indicates there are no errors.

1

INVALID CHAR

You sent the supply a character it did not recognize.

2

INVALID NUM

The format of your number is incorrect. Check syntax (see Chapter 5).

3 or 28

INVALID STR

You sent a command the supply does not understand. Resend a recognizable

 

 

command.

4

SYNTAX ERROR

You sent a command with improper syntax. Check syntax of your command

 

 

(see Chapter 5).

5

NUMBER RANGE

An out of range number was sent. Send a new number within the legal range.

6

NO QUERY

The computer addressed the supply to talk, but it did not first request data. Send

 

 

query first and then address the supply to talk.

7

DISP LENGTH

Quoted string in the DSP command exceeds the display length of 12 characters.

8

BUFFER FULL

May occur if too many numbers are sent. Error code 4 or error code 5 are more

 

 

likely to occur for this condition.

9

EEPROM ERROR

The EEPROM on the HP-IB board is not responding correctly to programming

 

 

commands. An instrument failure has occurred and service is required. Refer to

 

 

the Troubleshooting Section in the Service Manual.

10

HARDWARE ERR

An output error has occurred on an unknown output. Service is required. Refer

 

 

to the Troubleshooting Section in the Service Manual.

11HDW ERR CH 1 Error codes 11 through 14 refer to a specific output where an output error has occurred. Service is required. Refer to the Output Board Troubleshooting section in the Service Manual.

12

HDW ERR CH 2

Same as in error 11.

13

HDW ERR CH 3

Same as in error 11.

14

HDW ERR CH 4

Same as in error 11.

15

NO MODEL NUM

The supply's model number cannot be found. The HP-IB Interface board may be

 

 

defective or the supply may require reprogramming. Refer to the

 

 

Troubleshooting section of the Service Manual.

16

CAL ERROR

An error has occurred during calibration. This may be the result of out of range

 

 

numbers sent. If recalibration (See Appendix A) does not fix this there may be a

 

 

hardware failure (Refer to the Troubleshooting Section in the Service Manual).

6624A, 6621A, 6623A specifications

The HP 6623A, 6621A, and 6624A are precision DC power supplies widely recognized for their reliability and performance in various laboratory and industrial applications. These models are part of HP's 662X series, designed to cater to the needs of engineers, researchers, and technicians who require accurate power sources for their testing and development activities.

The main features of the HP 6623A, 6621A, and 6624A include their high stability, low ripple, and excellent load regulation, ensuring that the output voltage and current remain stable during testing. The power supplies provide multiple output channels, allowing users to power multiple devices simultaneously. The flexibility in setting voltage and current levels makes these models ideal for a wide range of applications, including semiconductor testing, device characterization, and system integration.

One of the standout technologies in the HP 662X series is the use of smart design techniques that minimize noise and enhance output performance. These power supplies incorporate advanced feedback mechanisms to maintain steady output, even under varying load conditions. Additionally, they feature programmable outputs, which means users can adjust the output levels through a connected computer or control system, streamlining the testing process and improving efficiency.

The HP 6623A model offers three independent outputs, with total power capabilities of 40 watts. It includes a 0-20V output, which can deliver up to 2A of current, along with two additional outputs that are adjustable. The 6621A provides a single output option, delivering a maximum of 20V and 2A, making it well-suited for simple applications where a single power source is required. In contrast, the HP 6624A stands out with its four independent output channels, providing a total of 60 watts, making it the most versatile of the three models.

Characteristics of these power supplies include user-friendly interfaces, allowing for easy configuration and monitoring of settings. LED indicators provide real-time feedback on voltage and current levels, enabling users to quickly assess the performance of their tests. Moreover, built-in protection features safeguard both the power supply and the connected devices from overvoltage and overcurrent conditions.

Overall, the HP 6623A, 6621A, and 6624A power supplies embody advanced engineering and design, making them invaluable tools for professionals looking for high-quality, reliable power sources for their electronic testing needs.
