SPECTRAN as an "EVENT RECORDER" for recording intermittent signals: just

leave SPECTRAN running in HOLD mode until the requested event occurs.

HOLD mode is also indispensible for conducting measurements according to the

panning approach (see also the section about "correct measurement")

Another application where HOLD mode is extremely helpful is exposure limit

calculation: You can use data acquired in HOLD mode for quick and easy com-

parison of exposure limits. You do not even need to start a new measurement,

as all markers and other relevant information are preserved. Please just switch

to exposure limits mode after measurement, and the corresponding result is

displayed immediately.

by pressing the dot key (switching it off deletes the HOLD memory).

ATTENTION: Please note that when using the Reference Level "Auto" setting in

combination with HOLD mode, the spectrum display can quickly get "filled up"

because of the automatic scaling. Such a combination of settings is generally of

limited use.

7.15 Unit (Select physical unit)

The Unit setting allows you to specify the physical unit used to display measu-

rement results. Options are "Tesla", "Gauss" and "A/m". Two further options,

"Volt" (external SMA connector) and "V/m" (E-field sensor) are automatically

chosen when the corresponding sensor is selected.

Hint: In "EXPOSURE LIMITS" mode, the measurement result additionally gets

displayed as a figure and bargraph. In this mode you can display the result with

two units AT ONCE (for example, Gauss and Tesla SIMULTANEOUSLY).

Hint2: You can even use this feature for conversion of units. Simply "freeze" the

current reading by using HOLD mode, then choose a different unit. The conver-

sion result will be displayed immediately (as far as physically possible).

A typical measurement result after evaluating a room for 20 minutes

with HOLD mode active. You can clearly see that only two main signal

sources / frequency bands have been detected during the entire mea-

surement (30Hz and 50Hz).

HINT: You can switch HOLD mode on and off at any time
