Key Sequence: Setup
PTC-ITCR Analyzer Setup Menu
Rx Pattern
Selects the receiver Bit Error Rate pattern. Select a pattern from the list box with the arrow keys or rotary knob and press Enter. There are two available patterns:
PN9 Cont
PN9 Burst
Symbol Rate
Selects the symbol rate for the signal generator when using the standard PTC patterns. Options are Half Rate (8 ksps) or
Full Rate (16 ksps).
Also sets the receiver IQ pattern deviation.
Tx Pattern
Selects the transmitter pattern to send when the Turn Sig‑Gen ON main menu key is pressed. Select a pattern from the list box with the Arrow keys or rotary knob, and then press Enter.
Patterns include PN9 continuous and burst (with repeating or
sequential payloads) at Half Rate or Full Rate, CW, AM 1 kHz audio, and FM 1 kHz audio.
Two submenu keys appear only with specific Tx Pattern settings:
AM Percentage: When am_1khx_audio is selected as the TX pattern, this submenu key displays to allow the setting of the percentage of the Amplitude modulation. The range is 0 % to 100 %.
FM Deviation: When fm_1khx_audio is selected as the TX pattern, this submenu key displays to allow the setting of the cycle count of the frequency deviation. The range is 0 Hz to 100 kHz.
Squelch Lvl
Sets the squelch power level. When the Received Power is lower than the set squelch level, all summary graph measurements except for Received Pwr will be blanked out (--).

Averaging: Sets the refresh rate of the numerical values in the Summary Table. Setting a higher number (25 maximum) will reduce measurement jitter.
Burst Trigger: Turns the Burst Trigger On or Off. When turned ON, the PTC analyzer will wait for the input signal to cross the Trigger Level signal threshold (set below) before capturing and analyzing the data. When turned Off, the PTC-ITCR analyzer captures and analyzes the signals continuously.
Trigger Level: Sets the minimum power level of the signal required to activate the burst trigger when Burst Trigger is On.
Time Out: Sets the trigger time out value. The display will not update while waiting for a trigger. When the “time out” duration elapses, the display is updated even if there is no trigger detected. The instrument provides an audible sound and displays a message to adjust the trigger level.
