Pressing FLTR TYPE a second time will return the system to the previous mode.
[active keys: ⇑/⇓, CH1/CH2, FLTR TYPE, ENT, FLTR MEM, REM CTL,]
This function key allows the user to place the Model 9002 under the operation of the remote controller and displays
the presently assigned address of the instrument. The address can be changed using the ⇑/⇓ keys. Only addresses
0-31 are valid. After entering the address, press the ENT key to transfer control to the remote controller. This will
light the REM indicator.
Once the system is under remote control, the only active key is REM CTL. Depressing this key a second time at any
stage of this procedure will return control of the Model 9002 to the front panel.
[inactive key: HZ/KHZ]
This key steps the display through the three filter parameter states while turning on the appropriate LED indicator.
The steps in sequence are:
Pre-filter gain
Post-filter gain
Filter Frequency
[inactive key: HZ/KHZ]
The method for changing gain is the same for both Pre- and Post-gain.
The PRE and GAIN LEDs will be lighted. The display will show the Pre-gain setup for the presently selected channel
and filter configuration number.
The gain has a range from 1.00-13.75 in incremental steps of 0.05. The numeric keypad or ⇑/⇓ keys are used to
change the gain. The suggested method for gain change is as follows:
Enter the gain value on the keypad
Press ENT to store the data
The ⇑/⇓ keys store the gain on-line and the ENT key need not be pressed. These keys will increase or decrease
gain by one increment, that is, 0.05. Gain will change as long as the key is depressed. The value displayed will auto-
matically be stored in the present filter configuration number and selected channel. Pressing CH1/CH2 will display
the Pre-gain of the selected channel.
Pressing the FREQ/GAIN key a second time will put the unit in the filter Post-gain setup.
[inactive key: HZ/KHZ]
The POST and GAIN LEDs will be lighted. The display shows the Post-filter gain of the selected channel and filter
configuration number. Post-gain operation is the same as Pre-gain operation and CH1/CH2 will display the Post-gain
of the selected channel.
Pressing FREQ/GAIN a third time will place the system in the filter-frequency setup.
