4.FRONT PANEL DESCRIPTION AND INITIAL SET UP

4.1General - Before turning on your HP3586 be sure it’s configured for the right input power, usually 115VAC. Also be sure the filter on its back panel is clean, if not remove it and clean with only soap and water. The filter should be cleaned after every 720 hours of operation.

In the following sections and chapter you’ll see capital letters in brackets like [AUTO]. These identify buttons used to control the instrument or enter data. The front panel of a HP3586 is broken into groups or sub panels, which we’ll refer to in this chapter to aid in locating individual displays and controls.

Additionally, on the front panel you will see some buttons with a second label below the button or two labels on the button like buttons near the keyboard, these are dual function buttons. Ones with two labels on the button will select the proper function automatically by the button that is previously pushed, like if you push [FREQ] the instrument knows MHz, KHz, or Hz apply instead of the other labels like –db or -db. The ones with labels below and above the button are shifted button. On the same panel you will see an unlabeled colored shift button with a light on it. When it’s light is on, the lower label of the dual-purpose adjacent buttons will apply. Also buttons with lights will have their function on when their light is on.

Plug you HP3586 into AC power and the STANDBY annunciator should light, next turn on your HP3586 by pressing [POWER]. It will first perform an auto calibration for about 5 seconds. If a ERR or CE with a number is displayed on the LH front panel read out there has been an error during calibration, refer to Appendix A for a listing of errors and suggested corrective action. The [AUTO CAL] button light should be on but you can turn off auto cal at any time by pressing this button, but for now leave it on. After the initial power up and auto cal the instrument should default to the low distortion-measuring mode with a range setting of 10db auto. During the following sections we will describe the front panel controls. Since the instrument will default to the selective low distortion level measuring mode when first it’s powered up you may not need to perform all the described button pushing commands but just confirm that the instrument is set up as described.

During the following sections of this chapter, have your HP3586 available in front of you to find the described controls and LED displays.

4.2Measurement/Entry Group - On the upper LH is the measurement/entry sub panel, which is used for displaying the power or voltage measurements and their units on a LED display. The measuring range and range full scale range value is set using it’s buttons. Set the range by pressing [10db] and the full scale range limit by pressing [AUTO] for the automatic mode. The analog meter reads the relative level of signals within the selected 100db or 10db range. With the 100db and auto settings this meter will work as a relative signal strength meter to aid in frequency tuning. Press [dbm] to have the display read in dbm units. A dbm annunciator should now light to indicate the units are shown in dbm. The [OFFSET] button is used to subtract values placed in an offset register that will be subtracted from level values computed by the instrument to correct or normalize displayed level values. We will discuss this feature later, for now leave it off. Other buttons we’ll discuss later during some of the examples.

4.3Frequency/Entry Group - On the upper RH side of the front panel is the frequency/entry sub panel. This panel will usually display the frequency that the instrument is tuned to. It will display during frequency entry frequencies being entered by the instrument’s keyboard in KHz or Hz. This frequency will be the center RF frequency of the selected band pass filter except when in the SSB channel measurement modes. On all models this panel can select a LSB or USB, side band channel for measurement using the two channel buttons with a funny symbol I can’t show with Word. The left button is for LSB while the one on the right is for USB. A counter button is provided to start the frequency measurement counter system. Only the A and B versions have the SSB entry frequency selection buttons. The carrier button should be on when in one of the SSB channel modes and tuning a SSB signal. This changes the display to read SSB carrier frequency instead of filter center RF frequency. Even when their lights are on, the tone

B, 3586A, C specifications

The HP C3586A and C3586B tape drives are notable components in the realm of data storage solutions, primarily designed for enterprise-class environments. These SCSI (Small Computer System Interface) tape drives are regarded for their efficiency, reliability, and capacity to meet the growing demands of data backup and archival processes in businesses.

The C3586A model utilizes the DAT (Digital Audio Tape) technology, which allows it to deliver high performance and high data density. It features a native capacity of 2.3 GB per cartridge, which can be extended to 4.6 GB with the use of compression. This is particularly advantageous for businesses requiring significant amounts of data storage without the necessity for multiple tapes. The transfer rate is rated at up to 12 MB per minute, which ensures quick backups and restores, minimizing the operational downtime.

In terms of data integrity and security, both models incorporate advanced error correction techniques to guarantee that data remains pristine and intact throughout the storage duration. They are designed to work seamlessly with a variety of operating systems and backup applications, enhancing compatibility and user convenience.

The HP C3586B, on the other hand, offers similar foundational technologies but with enhanced features. It supports higher capacity tapes and is engineered to work seamlessly in high-performance environments. With the integration of SCSI-2 interfacing, users can expect faster data transfer rates, which is critical for organizations dealing with large volumes of data.

Another key aspect of both models is their rugged design, which provides durability and reliability needed for long-term storage solutions. The drives are built to withstand extended usage, which makes them a cost-effective choice for businesses looking to invest in dependable data storage systems.

Furthermore, these drives come with a user-friendly interface and straightforward maintenance. This allows IT personnel to handle backups with ease while keeping the workflow uninterrupted.

In summary, the HP C3586A and C3586B tape drives epitomize the union of technology, usability, and dependability. Their robust features, including high data capacity, fast transfer rates, and durable construction, make them a formidable choice for enterprises seeking efficient data backup and archival solutions in the ever-evolving digital landscape.
