SPIMISO and SPIMOSI signals are tied together. SPISEL

module generates the MODINTR1 signal on the Processor

one interrupt to the CPU. The CPU can then decode which
module asserted the interrupt. Pull-up resistors for these
signals are located on the Processor board.

Unlike the HPC however, the platform manages power to the instrument module.

The platform shuts down power to the instrument module by pulling their
respective MODON control signals low and then cutting the power. During power
on from the suspend or shutdown state, the instrument module power supplies are
turned on first and then the module is turned on using the MODON signals.

Theory of Operation

The power modes

are:

Suspend mode. The platform automatically enters shutdown mode to save
battery power

following a period of instrument inactivity, or when you press
the front panel power button. You can set the length of this inactivity from the
Start > Settings > Control Panel > Power Management > Power Saver
tab. Before entering this mode, registry information and nonvolatile memory
are backed up and all nonessential power supplies shut down. LCD backlights
are turned off and the touch-screen display is inactivated. The instrument
module wil

l also be shut down.

During suspend mode, the real-time clock and SDRAM refresh remain active.
To return

from this state, you must press the front-panel pow er switch to

power up the platform, which takes approximately one minute.

Display

Power Saver mode. The front-panel status indicator changes from

Green to Amber to indicate the display Power Saver mode. In this state, the
display and backlight are turned off to save power. Instrument modules
remain powered on. Pressing the front-panel power switch cancels the Power
Saver mode and returns the platform to an active state. Measurements that are
running when you enter this mode continue to run.

this problem. If the platform remains in shutdown mode for more than two
hours, the processor system, with the exception of the real-time clock, is
completely powered off.

Transition to the power-down state occurs when the shutdown state timer
times-out or the internal batteries becomes critically low. Pressing the
front-panel power switch reactivates the internal circuitry and returns the
platform to an active state.

Internal Supplies to Module. In addition to the power requirements of the internal
circuit boards, the platform provides the following voltages to the instrument
module.

Power Sources. The platform and module can operate from the following
supplies:

Batteries. Powers the instrument using up to two Inspired Energy type
NI2020HD24 10.8 V, 7200 mAH, Li-ion batteries.

External Supply (DC or AC): Powers the instrument from a 24 VDC ±10%
external source. If the external supply is connected while the platform is

ting, the internal batteries will be disconnected without interrupting

opera
service. If the external supply is disconnected during service, the internal
batteries are connected without disrupting service.

Fuse Protection is provided by an automatic resetting fuse device. This fuse is
located in the external DC supply line on the Battery board. Requires no user
intervention.

Internal Charger. The sequential internal charger will charge a single 7200 mAH

ttery in approximately 4.5 hrs (two batteries requires approximately 9 hrs) if the

ba
platform is in shutdown mode. If the platform is operating, charging takes place
at a reduced rate in order to maintain internal temperatures within limits and to
avoid exceeding the capacity of the external supply. The charger is capable of
determining the battery technology type and appropriate charging sequence, and
is optimized for battery packs with nominal terminal voltages of between 7.2 and
12 volts. The maximum charging current is approximately 1.8 A in shutdown
mode and 0.8 A in the power on mode.

If the Desktop Power Supply or In-Vehicle Power Adapter is connected, the
internal batteries will charge if their capacity is low.

Charge Status Indicator. Low Battery Warning: Red indicates a low battery (less
than 20% remaining capacity). Green indicates battery charging. The platform
backs up current data and executes an orderly shutdown before complete loss
of battery power.

Measurement Module

If two batteries are installed, you can remove and replace either battery
without disrupting service.

If a second battery is installed, the platform automatically switches operation
to the second battery when the first battery reaches cut off capacity (5%
reserve) or is removed. The transition is transparent and does not interrupt
service.

Battery Power Management Utility. The Batteries tab in the Power Management
dialog box provides general information on battery status. This is the most
accurate information to determine battery charge status and probable manufacture
dates. (See page 60, H500 and SA2500 Instrument-Specific Battery Maintenance.)

The Measurement module contains no user-servicable parts. There are also no user
adjustments on the Measurement module. The entire instrument must be returned
for service. Service for the measurement module is not independently available.

Battery Maintenance

Use only Tektronix-approved batteries in your Tektronix products.

Do not leave batteries unused for extended periods of time, either in the product

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose
their capacity to hold a charge. This loss of capacity (aging) is irreversible. As
the battery loses capacity, the length of time it will power the product (run time)
decreases.

Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in
use or while in storage. Routinely check the battery’s charge status. The product

using a new instrument, or when you install new batteries. Set up a schedule to
check and record the battery charge and calibration status. See the Checking the
Battery Charge Status section in this document.

Compare the charge time and instrument run times with those for new batteries at
least every six months. When any of the following behaviors occur, you should

After the battery is fully charged, the instrument run time is significantly
shorter (<80%) with older fully-charged batteries than it is with new batteries.

A charge cycle never completes.

The Power Management Batteries tab does not show a Fully Charged status

Normal - updates display with each new result
Max Hold - updates displayed point only if new point > old
Min H old - updates displayed point only if new point < old
Max/MinHold-displaysavertical bar between Max Hold and Min Hold
Average - displays average of N (specified by user) acquisitions

Average is calculated as follows:

Last N values are saved in memory; when a new result is available,
the earliest result of the N stored values is discarded, the new result
is added to the stored values, and a new average is calculated from
the stored values
If the number of results is less than N, then all of the results are
averaged together
